feat: back-port design system utilities from tinker_tickets to web_template

Sticky footer layout:
- body: add display:flex + flex-direction:column
- .lt-main: add flex:1 + width:100% + min-width:0 so it fills remaining height
- .lt-main.lt-container combined-selector specificity fix (prevents lt-container
  padding from overriding lt-main padding-top in responsive breakpoints)
- Responsive breakpoints updated to use .lt-main.lt-container combined selector

Modal utilities:
- .lt-modal-xs (280px), .lt-modal-sm (360px) — size modifiers
- .lt-modal-header--danger — danger variant (red bg tint + accent border/title)

Badge:
- .lt-badge-sm — compact size (0.5rem font, 0.05/0.3rem padding)

KV rows:
- .lt-kv-row (display:contents), .lt-kv-label, .lt-kv-value — alternate KV
  row pattern where children become direct lt-kv-grid items

Avatar image overlay:
- .lt-avatar: add position:relative so img can overlay initials
- .lt-avatar img: use absolute inset:0 overlay (was flat width/height)
- .lt-avatar img.lt-avatar-img-err: display:none when JS marks broken image

Extended markdown styles:
- list-style: disc/decimal + colored ::marker (cyan/orange)
- mark, del, sub, sup, task-item, task-cb, task-done, task-todo
- Footnote helpers: fn-ref, fn-hr, fn-list, fn-item, fn-back
- .md-image alias on img rule

Footer keyboard hints:
- .lt-footer-hints, .lt-footer-hint, .lt-footer-key, .lt-footer-sep

+# Authelia Portal — LotusGuild Terminal Design System Integration
+
+This document covers everything that had to be **written from scratch** to theme the
+Authelia authentication portal using the LotusGuild Terminal Design System v1.2.
+It is a companion to `base.css` / `base.js` for future integrations with third-party
+applications that use their own component frameworks.
+
+---
+
+## Why a separate file at all?
+
+`base.css` targets exclusively `.lt-*` class names — the design system's own prefix.
+Authelia's frontend is a React single-page application built on
+**Material UI (MUI) v5**, which generates its own stable class names like
+`.MuiCard-root`, `.MuiButton-containedPrimary`, etc.
+Bridging the two requires a translation layer: the same design tokens and visual
+patterns from `base.css`, re-expressed against MUI's class structure.
+
+Additionally, Authelia v4.x (latest: 4.39.x) does **not** support native CSS
+injection — `server.asset_path` only handles `logo.png` and `favicon.ico`.
+The CSS is injected via **nginx `sub_filter`** in Nginx Proxy Manager, which rewrites
+Authelia's HTML on the fly to include a `<link>` tag before `</head>`.
+
+---
+
+## Deployment architecture
+
+```
+Browser
+  └─► https://auth.lotusguild.org  (NPM — LXC 139)
+        ├─ GET /custom.css  ──────── served from /data/custom_assets/authelia-custom.css
+        │                            (nginx alias, no upstream request)
+        └─ GET /*  ──────────────── proxied to Authelia (LXC 167 :9091)
+                                     HTML response is rewritten by sub_filter:
+                                     </head>  →  <link rel="stylesheet" href="/custom.css"></head>
+```
+
+**NPM config changed:** `/data/nginx/proxy_host/29.conf` (auth.lotusguild.org proxy host)
+
+```nginx
+# Serve LotusGuild Terminal custom CSS
+location = /custom.css {
+    alias /data/custom_assets/authelia-custom.css;
+    add_header Content-Type "text/css";
+    add_header Cache-Control "public, max-age=3600";
+}
+
+location / {
+    ...existing headers...
+
+    # Prevent upstream gzip so sub_filter can inspect the body
+    proxy_set_header Accept-Encoding "";
+
+    # Inject CSS link before </head>
+    sub_filter '</head>' '<link rel="stylesheet" href="/custom.css"></head>';
+    sub_filter_once on;
+
+    include /etc/nginx/conf.d/include/proxy.conf;
+}
+```
+
+> **Warning:** NPM regenerates proxy_host conf files when you edit a proxy host in
+> the UI. If host 29 is ever modified through NPM, re-apply the `sub_filter` block
+> and the `/custom.css` location manually, or set the config via NPM's
+> "Advanced" tab before saving.
+
+**Authelia config changed:** `/etc/authelia/configuration.yml` — added `asset_path`
+under `server:` so Authelia serves the resized logo and favicon:
+
+```yaml
+server:
+  address: tcp://0.0.0.0:9091
+  asset_path: /etc/authelia/assets
+```
+
+Assets in `/etc/authelia/assets/`:
+- `logo.png` — 256 × 256 PNG resized from Tinker Tickets `assets/images/favicon.png`
+- `favicon.ico` — 32 × 32 ICO from the same source
+
+---
+
+## What is NOT in `base.css` and had to be written
+
+The sections below are ordered as they appear in `authelia-custom.css`.
+
+---
+
+### 1. Re-declaring design tokens with `!important`
+
+**In `base.css`:** `:root { ... }` is declared once, without `!important`.
+
+**What had to be added:** The entire `:root` block is repeated in `custom.css` because
+Authelia's HTML is a self-contained SPA — `base.css` is never loaded. More critically,
+MUI injects its own inline styles and CSS-in-JS rules at very high specificity.
+Every property that needs to override MUI requires `!important`. `base.css` never
+uses `!important` because it owns its namespace; here we are guests in MUI's DOM.
+
+```css
+/* base.css does NOT use !important anywhere */
+body { background-color: var(--bg-primary); }
+
+/* custom.css must fight MUI's inline styles */
+body { background-color: var(--bg-primary) !important; }
+```
+
+The token values themselves are identical to `base.css` — only the override
+mechanism is new.
+
+---
+
+### 2. Universal box-sizing reset with `!important`
+
+**In `base.css`:** `*, *::before, *::after { box-sizing: border-box; }` — no flag needed
+because `base.css` loads first.
+
+**What had to be added:**
+
+```css
+*, *::before, *::after {
+  box-sizing: border-box !important;
+}
+```
+
+MUI components set `box-sizing` inline on some elements. Without the flag the
+clip-path geometry breaks on inputs and buttons.
+
+---
+
+### 3. MUI typography selectors
+
+**In `base.css`:** Typography rules target `h1–h6`, `a`, `p`, `body` — standard HTML
+elements. No MUI class names exist in the design system.
+
+**What had to be added:** Authelia renders text almost exclusively through MUI's
+`<Typography>` component, which produces elements with `.MuiTypography-root` and
+variant classes. Without targeting these, all text inherits MUI's Roboto font and
+light grey colour instead of JetBrains Mono and `--text-primary`.
+
+```css
+.MuiTypography-root,
+.MuiInputBase-input,
+.MuiFormLabel-root,
+.MuiFormHelperText-root,
+label, p, span, div {
+  font-family: var(--font-mono) !important;
+  color: var(--text-primary) !important;
+}
+
+h1, h2, h3, h4, h5, h6,
+.MuiTypography-h5,
+.MuiTypography-h6 {
+  color: var(--accent-orange) !important;
+  text-shadow: var(--glow-orange) !important;
+  ...
+}
+```
+
+---
+
+### 4. `.MuiCard-root` / `.MuiPaper-root` — the login card
+
+**In `base.css`:** `.lt-card` implements the terminal card with `clip-path`, border,
+background, and the `::before` corner triangle accent.
+
+**What had to be added:** Authelia wraps its login form in a MUI `<Card>` (which
+extends `<Paper>`). Neither selector exists in `base.css`. The visual result is
+identical to `.lt-card` — the clip-path polygon, cyan border, box-glow, and
+corner triangle are all copied — but they target different class names and require
+`!important` throughout to override MUI's elevation shadows and `border-radius: 4px`.
+
+```css
+.MuiCard-root,
+.MuiPaper-root {
+  background: var(--bg-card) !important;
+  border: 1px solid var(--border-color) !important;
+  border-radius: 0 !important;           /* ← overrides MUI default */
+  clip-path: polygon(...) !important;    /* same geometry as .lt-card */
+  ...
+}
+
+.MuiCard-root::before,
+.MuiPaper-root::before {
+  /* same corner triangle as .lt-card::before */
+}
+```
+
+---
+
+### 5. Logo element — `img[alt="Authelia"]`
+
+**In `base.css`:** No equivalent. The design system has no logo slot component.
+
+**What had to be added:** Authelia renders the portal logo as
+`<img alt="Authelia" src="./static/media/logo.png">`. This selector targets it
+specifically to apply the cyan drop-shadow and orange hover glow. Without it the
+logo renders without any terminal aesthetic treatment.
+
+```css
+img[alt="Authelia"] {
+  filter: drop-shadow(0 0 12px rgba(0,212,255,0.4)) !important;
+  transition: filter 0.25s ease !important;
+}
+img[alt="Authelia"]:hover {
+  filter: drop-shadow(0 0 18px rgba(255,107,0,0.5)) !important;
+}
+```
+
+---
+
+### 6. MUI outlined input family
+
+**In `base.css`:** `.lt-input`, `.lt-select`, `.lt-textarea` — custom elements with
+`clip-path`, terminal background, and cyan focus ring.
+
+**What had to be added:** MUI's outlined text field is a composition of three
+separate elements that each need individual targeting:
+
+| MUI class | What it controls | Equivalent in `base.css` |
+|-----------|-----------------|--------------------------|
+| `.MuiOutlinedInput-root` | Outer wrapper — background, clip-path | `.lt-input` outer |
+| `.MuiOutlinedInput-notchedOutline` | The SVG border element | `.lt-input` border |
+| `.MuiInputBase-input` | The actual `<input>` inside | `.lt-input` inner text |
+| `.MuiInputLabel-root` | Floating label | `.lt-label` |
+| `.MuiFormHelperText-root` | Error / hint text below field | `.lt-form-hint` |
+
+MUI splits the border rendering into a separate SVG `<fieldset>` element
+(`.MuiOutlinedInput-notchedOutline`), which requires its own border-color override.
+`base.css` has no equivalent splitting since `.lt-input` is a single element with a
+CSS border.
+
+The `.Mui-focused` and `.Mui-error` state classes also need explicit overrides because
+MUI applies its own colour through CSS-in-JS with high specificity.
+
+```css
+.MuiOutlinedInput-root.Mui-focused .MuiOutlinedInput-notchedOutline {
+  border-color: var(--accent-cyan) !important;
+  box-shadow: var(--box-glow-cyan) !important;
+}
+.MuiFormHelperText-root.Mui-error {
+  color: var(--accent-red) !important;
+  text-shadow: var(--glow-red) !important;
+}
+```
+
+Additionally, `caret-color` is set explicitly on the input because MUI does not
+expose this through its theme — the blinking text cursor would otherwise be white.
+
+---
+
+### 7. MUI button family
+
+**In `base.css`:** `.lt-btn`, `.lt-btn-primary`, `.lt-btn-danger`, `.lt-btn-ghost` —
+all using `clip-path` hexagon cuts, transparent backgrounds, and border+glow styling.
+
+**What had to be added:** MUI uses four separate button variant classes. The primary
+(sign-in) button is `.MuiButton-containedPrimary` which by default renders as a
+solid filled rectangle. The entire button appearance — transparent background,
+border, clip-path, text-transform, letter-spacing — has to be explicitly overridden
+because MUI's `contained` variant applies an opaque `background-color` inline.
+
+```css
+/* MUI default: background-color: #1976d2; border-radius: 4px; box-shadow: ... */
+.MuiButton-containedPrimary {
+  background: transparent !important;   /* fight the inline fill */
+  border: 1px solid var(--accent-orange-border) !important;
+  border-radius: 0 !important;
+  clip-path: polygon(...) !important;
+  ...
+}
+```
+
+Text/link buttons (`.MuiButton-text`) are separate from contained buttons in MUI but
+map to the same `.lt-btn-ghost` pattern in `base.css`.
+
+---
+
+### 8. MUI checkbox and switch
+
+**In `base.css`:** `.lt-checkbox`, `.lt-switch` — fully custom-drawn using CSS only.
+
+**What had to be added:** Authelia uses MUI's `<Checkbox>` (remember-me) and
+`<Switch>` (settings toggles). These are SVG-based components. Because MUI controls
+their colour through injected CSS variables, the only reliable override is to target
+`.Mui-checked` state classes and use `!important`. There is no equivalent split
+between `track` and `thumb` in `base.css`.
+
+```css
+.MuiSwitch-switchBase.Mui-checked { color: var(--accent-cyan) !important; }
+.MuiSwitch-switchBase.Mui-checked + .MuiSwitch-track {
+  background-color: var(--accent-cyan) !important;
+  opacity: 0.5 !important;
+}
+```
+
+---
+
+### 9. MUI alert / notification banners
+
+**In `base.css`:** `.lt-inline-*` for inline messages (`.lt-inline-success`,
+`.lt-inline-error`, etc.) and `.lt-toast-*` for toasts. These use a left border
+accent pattern.
+
+**What had to be added:** Authelia uses MUI `<Alert>` for login errors, success
+messages, and 2FA prompts. MUI Alert has its own severity system with four variant
+classes (`.MuiAlert-standardError`, etc.). Each severity needs explicit colour,
+background, and border-color overrides. The `border-left: 3px solid currentColor`
+pattern is adapted from `base.css`'s inline message style but applied to MUI's
+class names with `clip-path: none !important` to cancel MUI's rounded corners.
+
+---
+
+### 10. MUI select, menu, and popover
+
+**In `base.css`:** `.lt-select` for the select element itself; no dropdown overlay
+component exists since the design system uses native `<select>`.
+
+**What had to be added:** MUI's `<Select>` renders its dropdown as a `<Paper>`
+element portalled to `<body>` with class `.MuiMenu-paper`. Without targeting this
+separately, the dropdown popup inherits the browser default white background and
+Roboto font, appearing completely unstyled. `.MuiMenuItem-root` hover and selected
+states also need individual rules.
+
+---
+
+### 11. OTP / 2FA digit inputs — `input[type="tel"]`, `input[type="number"]`
+
+**In `base.css`:** No equivalent. The design system has no numeric code input.
+
+**What had to be added:** Authelia's one-time-password entry uses `<input type="tel">`
+elements arranged in a row. These need oversized, centered, cyan-glowing characters
+with wide letter-spacing to render like a retro code display.
+
+```css
+input[type="tel"],
+input[type="number"] {
+  font-size: 1.2rem !important;
+  font-weight: 700 !important;
+  color: var(--accent-cyan) !important;
+  text-shadow: var(--glow-cyan) !important;
+  letter-spacing: 0.15em !important;
+  text-align: center !important;
+  caret-color: var(--accent-orange) !important;
+}
+```
+
+---
+
+### 12. MUI stepper — 2FA flow breadcrumb
+
+**In `base.css`:** `.lt-stepper`, `.lt-step`, `.lt-step-num` — a custom CSS stepper
+for multi-step wizard flows.
+
+**What had to be added:** Authelia renders a MUI `<Stepper>` at the top of the 2FA
+flow showing steps like "Username → Password → TOTP". MUI Stepper uses distinct
+classes for label, icon, and connector that don't map 1-to-1 to `.lt-step-*`.
+The step icon is an SVG circle rendered by React so it can only be tinted via
+`color` and `filter: drop-shadow(...)`. The connector line between steps is a
+separate `<hr>` with class `.MuiStepConnector-line`.
+
+```css
+.MuiStepIcon-root.Mui-active {
+  color: var(--accent-orange) !important;
+  filter: drop-shadow(0 0 6px rgba(255,107,0,0.6)) !important;
+}
+.MuiStepIcon-root.Mui-completed {
+  color: var(--accent-green) !important;
+}
+```
+
+---
+
+### 13. MUI linear and circular progress
+
+**In `base.css`:** `.lt-progress` / `.lt-progress-bar` — a standard CSS progress bar
+using `width` transitions. `.lt-spinner` — a rotating pseudo-element spinner.
+
+**What had to be added:** Authelia uses MUI `<LinearProgress>` during API calls and
+`<CircularProgress>` as the main loading spinner. MUI Linear Progress animates its
+own internal elements (`.MuiLinearProgress-bar`) with keyframe animations; it cannot
+be replaced with the `.lt-progress` pattern. The cyan-to-orange gradient and
+`box-shadow` glow are new here — `base.css`'s progress bar uses a solid
+`--accent-orange` fill.
+
+```css
+.MuiLinearProgress-bar {
+  background: linear-gradient(90deg, var(--accent-cyan), var(--accent-orange)) !important;
+  box-shadow: 0 0 8px rgba(0,212,255,0.5) !important;
+}
+```
+
+---
+
+### 14. MUI tooltip
+
+**In `base.css`:** `.lt-tooltip` — a CSS-only tooltip shown via `:hover` on a
+`[data-tooltip]` attribute.
+
+**What had to be added:** MUI `<Tooltip>` portals its bubble to `<body>` with class
+`.MuiTooltip-tooltip`. It is a separate DOM node, not a pseudo-element, so
+`.lt-tooltip` styles cannot reach it. A standalone rule sets the terminal background,
+monospace font, and squared border.
+
+---
+
+### 15. `*:focus-visible` global ring
+
+**In `base.css`:** Focus rings are defined individually per component
+(`.lt-btn:focus-visible`, `.lt-input:focus-visible`, etc.).
+
+**What had to be added:** A single global rule is more practical here because
+Authelia contains many interactive MUI elements not known at design time, and
+adding per-component rules for every possible focusable element would be brittle.
+
+```css
+*:focus-visible {
+  outline: 2px solid var(--accent-cyan) !important;
+  outline-offset: 2px !important;
+  box-shadow: var(--box-glow-cyan) !important;
+}
+```
+
+---
+
+### 16. Branding footer watermark — `#root::after`
+
+**In `base.css`:** No equivalent. The design system does not add page-level
+watermarks.
+
+**What had to be added:** Authelia has no footer. The `#root::after` pseudo-element
+attaches a fixed-position text watermark reading
+`LOTUSGUILD SECURE PORTAL // AUTH.LOTUSGUILD.ORG` at the bottom of the viewport.
+This uses `--text-muted`, `--font-mono`, uppercase, and wide letter-spacing to match
+the terminal aesthetic without adding any HTML.
+
+```css
+#root::after {
+  content: 'LOTUSGUILD SECURE PORTAL // AUTH.LOTUSGUILD.ORG';
+  position: fixed;
+  bottom: 12px;
+  left: 50%;
+  transform: translateX(-50%);
+  font-size: 0.55rem;
+  letter-spacing: 0.18em;
+  color: var(--text-muted);
+  opacity: 0.6;
+  pointer-events: none;
+}
+```
+
+---
+
+## Patterns shared with `base.css` (not new)
+
+The following are **not** documented above because they are direct re-uses of
+existing `base.css` patterns, only re-targeted to new selectors:
+
+| Pattern | `base.css` source | Re-used in `custom.css` for |
+|---------|------------------|-----------------------------|
+| Dot-grid background | `html { background-image: radial-gradient(...) }` | `body` |
+| Scanlines overlay | `body::before` | `body::before` (same rule, `!important` added) |
+| Corner vignette | `body::after` | `body::after` (same rule, `!important` added) |
+| Card clip-path polygon | `.lt-card { clip-path: polygon(...) }` | `.MuiCard-root` |
+| Card corner triangle | `.lt-card::before` | `.MuiCard-root::before` |
+| Button clip-path hexagon | `.lt-btn { clip-path: polygon(...) }` | `.MuiButton-containedPrimary` |
+| Input clip-path cut | `.lt-input { clip-path: polygon(...) }` | `.MuiOutlinedInput-root` |
+| Scrollbar | `::-webkit-scrollbar-*` section 45 | identical, `border-radius: 0` added |
+| Link colours | `a { color: var(--accent-cyan) }` | `a` (same, `!important` added) |
+| Divider | `.lt-divider` border-color | `.MuiDivider-root` |
+
+---
+
+## Notes for future third-party integrations
+
+1. **Always check for `!important` requirements.** CSS-in-JS frameworks (MUI, Emotion,
+   styled-components) inject styles at runtime with high specificity. Without
+   `!important`, most design token overrides will lose to injected inline styles.
+
+2. **The split border problem.** MUI (and many component libraries) separate the
+   border from the element it visually belongs to. Always inspect the actual DOM
+   before writing selectors — what looks like one element is often three.
+
+3. **Portalled overlays.** Dropdowns, tooltips, and modals in MUI are rendered into
+   a separate DOM tree (`<body>` portal). Scoped selectors inside a card or form
+   won't reach them. Target their root classes (`.MuiMenu-paper`, `.MuiTooltip-tooltip`)
+   directly.
+
+4. **State classes.** MUI uses `.Mui-focused`, `.Mui-checked`, `.Mui-error`,
+   `.Mui-active`, `.Mui-completed`, `.Mui-disabled` as state modifiers. These are the
+   equivalent of `:focus`, `:checked`, etc. but applied by JavaScript — pseudo-class
+   selectors alone will sometimes not fire.
+
+5. **SVG-based components.** Checkboxes, radio buttons, step icons, and spinners are
+   SVGs injected by React. They cannot be styled with `background`, `border`, or
+   `clip-path`. Use `color` (SVG `currentColor` inheritance) and `filter:
+   drop-shadow()` instead.
