# LotusGuild Terminal Design System — v1.2 [![Lint](https://code.lotusguild.org/LotusGuild/web_template/actions/workflows/lint.yml/badge.svg)](https://code.lotusguild.org/LotusGuild/web_template/actions?workflow=lint.yml) **Aesthetic:** Anduril × Hacker Terminal — dark military-tech, multi-accent neon, angular clip-path frames, glitch effects. A single-file design system (`base.css` + `base.js`) used across all LotusGuild internal services. `base.html` is a living reference template that demonstrates every component and pattern. --- ## Table of Contents 1.

[LDAP Avatar Integration](#ldap-avatar-integration) 13. [Changelog](#changelog) --- ## Overview | File | Purpose | |------|---------| | `base.css` | All styles — ~5,200 lines, 79 sections | | `base.js` | All JS — vanilla IIFE, `window.lt` namespace, 55+ modules | | `base.html` | Full component reference / demo page | No build step. No npm. No framework. Drop in the two files and go. --- ## Quick Start ```html ``` ### `lt.init()` — master initializer `lt.init(opts?)` runs all standard auto-init modules in one call. Safe to call multiple times — a guard prevents double-initialization. ```js lt.init({ bootName: 'MY APP', // shown in CRT boot overlay (optional) skipBoot: false, // set true to skip the boot sequence csrf: 'token', // CSRF token string (optional; overrides meta-tag detection) }); ``` Modules initialized automatically: `tabs`, `accordion`, `tooltip`, `clipboard.initCopyButtons`, `alerts`, `sidebar`, `keys.initDefaults`, `mobileNav`. --- ## Design Tokens All tokens are CSS custom properties on `:root`. Override any token in your app stylesheet **after** importing `base.css`. ### Backgrounds | Token | Dark | Light | |-------|------|-------| | `--bg-primary` | `#030508` | `#edf0f5` | | `--bg-secondary` | `#060c14` | `#e2e8f0` | | `--bg-tertiary` | `#0d1520` | `#cdd5e0` | | `--bg-card` | `#07101a` | `#f5f7fb` | | `--bg-terminal` | `#010304` | `#d8dfe8` | | `--bg-overlay` | `rgba(3,5,8,0.94)` | `rgba(237,240,245,0.96)` | ### Text | Token | Dark | Light | |-------|------|-------| | `--text-primary` | `#e8edf5` | `#1a2233` | | `--text-secondary` | `#8899b0` | `#3a4a60` | | `--text-muted` | `#4a5a70` | `#6a7a90` | | `--text-accent` | `#FF6B00` | `#c44e00` | ### Borders | Token | Dark | Light | |-------|------|-------| | `--border-color` | `rgba(255,107,0,0.25)` | `rgba(130,140,160,0.5)` | | `--border-dim` | `rgba(255,107,0,0.10)` | `rgba(130,140,160,0.25)` | | `--border-bright` | `rgba(255,107,0,0.6)` | `rgba(196,78,0,0.5)` | ### Spacing `--space-xs` (0.25rem) · `--space-sm` (0.5rem) · `--space-md` (1rem) · `--space-lg` (1.5rem) · `--space-xl` (2rem) · `--space-2xl` (3rem) ### Layout | Token | Value | |-------|-------| | `--sidebar-width` | `240px` | | `--header-height` | `56px` | | `--container-max` | `1600px` | ### Transitions | Token | Value | |-------|-------| | `--transition-fast` | `all 0.12s ease` | | `--transition-default` | `all 0.25s ease` | ### Corner Cuts | Token | Value | Usage | |-------|-------|-------| | `--corner-cut` | `8px` | Standard clip-path notch | | `--corner-cut-sm` | `5px` | Small elements | | `--corner-cut-lg` | `16px` | Large modals / hero cards | ### Z-Index Ladder | Token | Value | Layer | |-------|-------|-------| | `--z-base` | `1` | Stacking context base | | `--z-dropdown` | `100` | Dropdowns, autocomplete | | `--z-sticky` | `200` | Sticky elements | | `--z-fixed` | `300` | Fixed header/sidebar | | `--z-overlay` | `9999` | CRT scanlines / boot overlay | | `--z-modal-backdrop` | `10010` | Modal scrim | | `--z-modal` | `10011` | Modal dialogs | | `--z-popover` | `10012` | Popovers | | `--z-tooltip` | `10013` | Tooltips | | `--z-toast` | `10014` | Toast notifications | | `--z-panel` | `10020` | Notification / dropdown panels | --- ## Breakpoints Mobile-first. 8 tiers: | Name | Range | CSS min-width | |------|-------|---------------| | `xs` | ≤ 479px | — (base) | | `sm` | 480–767px | `480px` | | `md` | 768–1023px | `768px` | | `lg` | 1024–1279px | `1024px` | | `xl` | 1280–1535px | `1280px` | | `2xl` | 1536–1919px | `1536px` | | `3xl` | 1920–2559px | `1920px` | | `4k` | ≥ 2560px | `2560px` | Check breakpoints in JavaScript: ```js lt.viewport.bp() // → 'xs' | 'sm' | 'md' | ... | '4k' lt.viewport.is('md') // → true if current bp >= md lt.viewport.on(cb) // subscribe to resize/bp changes lt.viewport.touch() // true if primary pointer is coarse lt.viewport.landscape() ``` --- ## Typography **Font:** JetBrains Mono (Google Fonts) — weights 400, 600, 700; italic 400.

Changes sync across browser tabs instantly via the `storage` event. The native `color-scheme` CSS property is also updated so browser UI (scrollbars, form controls) matches the current theme. ### CSS Only Set `data-theme="light"` on `` directly. All component styles react through the Section 51 overrides. --- ## Accessibility - All interactive elements have `role`, `aria-label`, `aria-expanded`, `aria-controls`, `aria-hidden` as appropriate. - Focus rings: `outline: 2px solid var(--accent-orange)` with `outline-offset: 2px`. - Screen-reader-only text: `…`. - Touch targets: all interactive elements are ≥ 44×44px on `pointer: coarse` devices. - `prefers-reduced-motion`: skeleton shimmer and boot animations are disabled. - `prefers-color-scheme`: theme is auto-detected on first load if no saved preference. - Keyboard navigation: arrow keys / Enter in tables, Ctrl+K for command palette, Escape closes modals / drawers / dropdowns. - Data tables require `…`. --- ## File Structure ``` web_template/ ├── base.css Design system styles (79 sections, ~5,200 lines) ├── base.js Design system JS (55+ modules, ~2,800 lines) ├── base.html Living reference template ├── README.md This file └── (framework skeletons) ├── php/ PHP / Tinker Tickets ├── python/ Flask / Jinja2 / GANDALF └── node/ Express / EJS / PULSE ``` --- ## LDAP Avatar Integration `lt-avatar` components support real profile photos pulled from **lldap** (the LotusGuild LDAP server). Photos overlay the initials fallback — if a user has no photo the initials show instead; no broken images. ### Infrastructure (one-time, per app) **1. Create a service account in lldap** Log into lldap at `http://10.10.10.39:17170`, or use the GraphQL API: ```bash TOKEN=$(curl -s -X POST http://10.10.10.39:17170/auth/simple/login \ -H 'Content-Type: application/json' \ -d '{"username":"","password":""}' | python3 -c "import sys,json; print(json.load(sys.stdin)['token'])") # Create service account curl -s -X POST http://10.10.10.39:17170/api/graphql \ -H "Content-Type: application/json" \ -H "Authorization: Bearer $TOKEN" \ -d '{"query":"mutation { createUser(user: { id: \"my-app\", email: \"my-app@lotusguild.org\", displayName: \"My App Service\" }) { id } }"}' # Add to lldap_strict_readonly (id=3) for directory read access curl -s -X POST http://10.10.10.39:17170/api/graphql \ -H "Content-Type: application/json" \ -H "Authorization: Bearer $TOKEN" \ -d '{"query":"mutation { addUserToGroup(userId: \"my-app\", groupId: 3) { ok } }"}' ``` Then set the password via `ldappasswd`: ```bash ldappasswd -H ldap://10.10.10.39:3890 \ -D "uid=,ou=people,dc=example,dc=com" \ -w '' \ -s '' \ "uid=my-app,ou=people,dc=example,dc=com" ``` **2. Install php-ldap and create the avatar cache directory** ```bash apt-get install -y php8.2-ldap mkdir -p /var/www/html/myapp/uploads/avatars chown -R www-data:www-data /var/www/html/myapp/uploads/avatars ``` **3. Add LDAP config to `.env`** ```ini LDAP_ENABLED=true LDAP_HOST=10.10.10.39 LDAP_PORT=3890 LDAP_BIND_DN="uid=my-app,ou=people,dc=example,dc=com" LDAP_BIND_PW="" LDAP_BASE_DN="dc=example,dc=com" LDAP_USER_BASE="ou=people,dc=example,dc=com" AVATAR_CACHE_TTL=3600 ``` > **Note:** lldap is currently configured with `dc=example,dc=com` as the base DN across all services (Authelia, etc.). Do not change this per-app — it requires a coordinated infrastructure migration. ### Avatar Endpoint (`/api/user_avatar.php`) Copy the reference implementation from `tinker_tickets/api/user_avatar.php`. It: 1. Requires a valid session (returns 401 otherwise) 2. Accepts `?user_id=N` and looks up the user's `username` from the app's DB 3. Binds to lldap and searches `ou=people,dc=example,dc=com` with filter `(uid={username})` 4. Fetches the `avatar` attribute (raw binary JPEG, returned as-is by `ldap_get_entries()`) 5. Validates JPEG magic bytes (`\xFF\xD8\xFF`) and writes to `uploads/avatars/user_{id}.jpg` 6. Writes a `.none` sentinel file for users with no avatar so lldap is not queried again until TTL expires 7. Serves the cached file with `Content-Type: image/jpeg` ### CSS — Photo-over-Initials Pattern `base.css` (Section 62 — Avatar) provides `.lt-avatar-img` and `.lt-avatar-initials`: ```css .lt-avatar { position: relative; } .lt-avatar-initials { position: absolute; inset: 0; display: flex; align-items: center; justify-content: center; } .lt-avatar-img { position: absolute; inset: 0; width: 100%; height: 100%; object-fit: cover; border-radius: inherit; z-index: 1; } ``` The photo sits above the initials. The `onerror` handler hides the image if the endpoint returns 404 (no avatar), letting the initials show through. ### HTML Pattern ```php $w[0], array_slice($words, 0, 2)))); $colors = ['lt-avatar--orange', 'lt-avatar--green', 'lt-avatar--purple', '']; $color = $colors[abs(crc32($displayName)) % count($colors)]; ?> ``` Key points: - Always render the initials — they are the fallback, never a broken state - The `onerror` on the `` hides it when the endpoint returns 404 (no photo set) - Color is deterministically derived from the display name so it's consistent across page loads - `aria-hidden="true"` because the avatar is purely decorative; the user's name appears in adjacent text --- ## Known Patterns & Gotchas ### Disabled / read-only form elements in display-only contexts `base.css` applies aggressive visibility reduction to `:disabled` and `[readonly]` form elements: ```css .lt-input:disabled, .lt-select:disabled, .lt-textarea:disabled, .lt-input[readonly], .lt-textarea[readonly] { opacity: 0.45; color: var(--text-muted); /* #3e607a — ~3.2:1 contrast, fails WCAG AA on dark backgrounds */ } .lt-checkbox:disabled { opacity: 0.4; } ``` This is intentional for *genuinely* disabled controls (submission forms, locked fields). However, if you use `disabled` purely to make a field **non-interactive for display**, the result is nearly unreadable on dark/OLED screens. **Pattern: display-only selects / inputs (edit-mode toggle)** A common pattern is disabling fields in view-mode and enabling them in edit-mode. Apply a scoping class and override in your app CSS: ```css /* In your app's CSS — override base.css fading for display-only fields */ .your-display-field:disabled, .your-display-field[disabled] { opacity: 1; color: var(--text-secondary); /* #7fa3bf — full legibility */ cursor: default; pointer-events: none; } ``` **Pattern: copy-to-clipboard inputs (readonly)** `[readonly]` triggers the same `opacity: 0.45` rule. For API key / token display fields where the user must read and copy the value, restore opacity inline or via class: ```html ``` **Pattern: description / content display areas** Avoid rendering multi-line content in a `disabled` textarea — use a styled `
` instead. Apply `white-space: pre-wrap` on that div to preserve newlines and multiple spaces (required for ASCII art / diagrams to align correctly, since the body font is already monospace): ```css .your-description-view { white-space: pre-wrap; word-break: break-word; color: var(--text-primary); } ``` Set `innerHTML = escHtml(rawText)` — no `
` replacement needed when `white-space: pre-wrap` is active. --- ## Changelog ### v1.2 (current) **Design System** - Font: Courier New → **JetBrains Mono** (400, 600, 700; italic) - Palette: phosphor-green single-accent → **5-accent neon system** (Orange #FF6B00, Cyan #00D4FF, Green #00FF88, Red #FF2D55, Purple #BF5FFF) - Background: green-tinted CRT → **Anduril dark military-tech** (`#030508`–`#0d1520`) - **Light mode rebuilt from scratch** (~200 lines, Section 51): desaturated accent colors, drop-shadow rings instead of neon glows, WCAG-accessible contrast on all 80+ component classes - Added `--corner-cut`, `--corner-cut-sm`, `--corner-cut-lg` CSS variables - Added `--z-panel` (10020) to z-index ladder; replaced all hardcoded z-index values - Added `will-change: transform` on `.lt-spinner`, `will-change: opacity` on `.lt-skeleton` - Removed duplicate `.lt-hidden` definition **New Components** - Notification bell: unread badge, animated dropdown panel, mark-all-read, per-item click-to-read, outside-click close - Generic dropdown widget: `.lt-dropdown-wrap` + `.lt-dropdown-panel` + `.lt-dropdown-trigger` - Editable ticket detail drawer: form grid, status/priority/assignee selects, description textarea, comment box - Advanced filter dropdown for ticket queue - Bulk actions dropdown with toast feedback - Footer landmark (`
