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 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
