CSS fixes:
- Fix [ ] brackets appearing below button text by replacing display:inline-flex
with display:inline-block + white-space:nowrap on .btn — removes cross-browser
flex pseudo-element inconsistency as root cause
- Remove conflicting .btn::before ripple block (position:absolute was overriding
bracket content positioning)
- Remove overflow:hidden from .btn which was clipping bracket content
- Fix body::after duplicate rule causing GPU layer blink (second position:fixed
rule re-created compositor layer, overriding display:none suppression)
- Replace all transition:all with scoped property transitions in dashboard.css,
ticket.css, base.css (prevents full CSS property evaluation on every hover)
- Convert pulse-warning/pulse-critical keyframes from box-shadow to opacity
animation (GPU-composited, eliminates CPU repaints at 60fps)
- Fix mobile *::before/*::after blanket content:none rule — now targets only
decorative frame glyphs, preserving button brackets and status indicators
- Remove --terminal-green-dim override that broke .lt-btn hover backgrounds
JS fixes:
- Fix all lt.lt.toast.* double-prefix instances in dashboard.js
- Add null guard before .appendChild() on bulkAssignUser select
- Replace all remaining emoji with terminal bracket notation (dashboard.js,
ticket.js, markdown.js)
- Migrate all toast.*() shim calls to lt.toast.* across all JS files
View fixes:
- Remove hardcoded [ ] brackets from .btn buttons (CSS now adds them)
- Replace all emoji with terminal bracket notation in all views and admin views
- Add missing CSP nonces to AuditLogView.php and UserActivityView.php script tags
- Bump CSS version strings to ?v=20260319b for cache busting
Security fixes:
- update_ticket.php: add authorization check (non-admins can only edit their own
or assigned tickets)
- add_comment.php: validate and cast ticket_id to integer with 400 response
- clone_ticket.php: fix unconditional session_start(), add ticket ID validation,
add internal ticket access check
- bulk_operation.php: add HTTP 401/403 status codes on auth failures
- upload_attachment.php: fix missing $conn arg in AttachmentModel constructor
- assign_ticket.php: add ticket existence check and permission verification
