Accessibility Pass

• Keyboard — every interactive element reachable and operable by Tab/Enter/Esc. Modals trap focus and restore it on close.
• Labels — every input has a real <label>; icon-only buttons have aria-label.
• Images — meaningful alt; decorative images alt="".
• Contrast — text ≥ 4.5:1 (3:1 for large). Don't encode meaning in color alone.
• Semantics — real <button>/<a>, not a clickable <div>. Headings in order.
• Focus — visible focus ring. Never outline: none without a replacement. Output: each failure with the element + the fix. Test it with Tab only, no mouse.
