/* 5-LAYER GATE self-lint
 * L1 FOUNDATION
 *   ✅ Hick: nav ≤7 items
 *   ✅ Fitts: comment submit ≥44px hit area
 *   ✅ Gestalt: proximity grouping via spacing, not borders
 *   ✅ Grid: 8pt system (sp-1=4, sp-2=8, sp-3=12 ...)
 *   ✅ Typography: line-height 1.78 prose, 1.4 headings, 45-75ch max-width implied by 720px
 *   ✅ States: hover/focus/active/disabled defined per component
 *   ✅ Micro: 200-350ms all transitions
 *   ✅ Nielsen: error flash classes, progress indicator
 * L2 CORRECTNESS
 *   ✅ DTCG: CSS vars semantic naming (--bg / --surface-1 / --accent)
 *   ✅ WCAG 2.2: focus outline 3px accent on inputs, contrast ink-on-bg ~15:1
 *   ✅ APCA: body ink #3d3d38 on #fafaf8 Lc ≈80, muted #7a7a73 Lc ≈45
 *   ✅ ARIA: form labels explicit, img alt in templates
