/**
 * TryVue — AI Shopping Assistant (storefront widget) styles.
 *
 * Enterprise, fully self-contained styling scoped under #tryvue-chat-root so it
 * never inherits or leaks into the host theme. Accent-driven via CSS custom
 * properties (set at runtime by tryvue-chat.js), light/dark via [data-theme].
 *
 * Layout philosophy (Claude / ChatGPT level):
 *   - Desktop/laptop: a compact floating panel anchored bottom-right with a
 *     sensible max-width/height, a sticky header, a flex-column scrollable
 *     message list, and a compact auto-growing composer.
 *   - Mobile: a full-height bottom-sheet using 100dvh + safe-area insets so it
 *     NEVER overflows the viewport and the header/composer are never clipped.
 *
 * @package TryVue

/* ── Access-mode: sign-in gate / invite (audience gating) ──────────────
   Four owner-selectable modes drive these UI affordances (server re-enforces):
     - members_prompt guest  → a full GATE replaces the composer (.tvc-authgate
       inside a .tvc-composer--gated footer) — read the greeting, must sign in.
     - everyone_prompt guest → a gentle INVITE banner (.tvc-authinvite) sits
       above a fully working composer — an upsell, never a block.
     - 401 login_required     → an INLINE gate (.tvc-authgate--inline) is
       appended to the transcript as an assistant row.
   All are accent-driven and theme-aware via the same tokens used elsewhere. */
