/* KAVVI SKILL SETTINGS (2026-10-07) - the sheet a skill's label opens (kv-skills-20261007.js),
   and the label itself inside the composer chip. App tokens only (the same ones as the
   workspace sheet, study-flow-20260927.css), so light/dark and RTL follow the app. */

/* ---------- the composer skill chip (polish-20261007: web/patch-chat-chip.cjs) ----------
   span.kv-sk-chip[data-skill] > button.kv-sk-label (icon tile, name + summary, settings pill) + button.kv-sk-x.
   fast-start-20260923.css styles every .composer-skill-chip part with !important (an 18px circle for
   every button, white text, a flat mint pill), so each rule here is !important at a higher specificity.
   Each skill has its own colour (--sk); everything else is mixed from it and the app's own tokens, so
   the chip reads in light and dark. key = the skill: choosing another one remounts it and it animates in. */
