Phase 0 — CSS-only fixes: - Fix --font-mono to use real monospace stack (JetBrains Mono, Fira Code, etc.) - Replace hardcoded hex colors with CSS variables across 16+ files - Merge global-nav.css (507 lines) into layout.css, delete original - Reduce !important in responsive.css from 71 to 8 via .app-shell specificity - Standardize breakpoints to 480/768/1024/1280px Phase 1 — Loading states & SSE connection feedback: - Add centralized SSEManager (sse-manager.js) with exponential backoff - Add SSE status indicator dot in nav bar - Add withLoadingButton() + .btn-loading CSS spinner - Add mode section crossfade transitions Phase 2 — Accessibility: - Add aria-labels to icon-only buttons across mode partials - Add for/id associations to 42 form labels in 5 mode partials - Add aria-live on toast stack, enableListKeyNav() utility Phase 3 — Destructive action guards & list overflow: - Add confirmAction() styled modal, replace all 25 native confirm() calls - Add toast cap at 5 simultaneous toasts - Add list overflow indicator CSS Phase 4 — Inline style extraction: - Refactor switchMode() in app.js and index.html to use classList.toggle() - Add CSS toggle rules for all switchMode-controlled elements - Remove inline style="display:none" from 7+ HTML elements - Add utility classes (.hidden, .d-flex, .d-grid, etc.) Phase 5 — Mobile UX polish: - pre/code overflow handling already in place - Touch target sizing via --touch-min variable Phase 6 — Error handling consistency: - Add reportActionableError() to user-facing catch blocks in 5 mode JS files - 28 error toast additions alongside existing console.error calls Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
