/* assets/components/ai-polish.css — dismissable AI-polish button widget (P3 Phase 1A).
 *
 * Companion to assets/components/ai-polish.js. Renders a small ✨ Polish
 * button below a textarea; on click, calls a configured endpoint and shows
 * the polished text inline with an Undo affordance.
 *
 * Used by: trial-setup.html Step 3 (preferenceText textarea); profile-
 * update.html (capability textarea); future subscriber-portal.html.
 *
 * Per charter (Phase 0 dispatch): small, dismissable, never required.
 * Per CLAUDE.md SR #94: model resolved server-side via ANTHROPIC_MODEL_HAIKU;
 * widget never references model name.
 *
 * Palette: teal text #007A62 (button text); accent #00D4AA (active state).
