/* ============================================================
   tryai - two tools, one quiet form vocabulary.

   Rules this file keeps to (2026-10-08 redesign):
   - Every input has a sentence-case label above it (.block-title) and, when
     it needs one, a single line of help (.block-help). No tracked uppercase
     eyebrows, no numbered badges, no nested accent boxes.
   - Text that carries meaning is never below 13px and never below 4.5:1
     against the ground it sits on, in either theme (--text-dim, --text-faint
     and --danger are tuned for that).
   - One accent, spent on the focused field, the primary button, the selected
     control and the answer. Everything else is ink on ground.
   - Focus is always visible; targets are at least 32px.
