/* ============================================================
   Puna Page Chat — feedback-chat widget chrome (BL-318 widget leg).

   Spec: _operating/_pending/BL-318-page-chat-spec.md § Widget.
   Two-copy module pattern: canonical source
     website/_components/feedback-chat/widget.css
   kept byte-identical to
     app/shared/feedback-chat/widget.css.

   Component-scoped palette per _config/design-tokens.md — tokens
   declared on .fc-root itself, never on :root. Canonical brand
   values resolve from design-tokens.css when the consuming page
   loads it; inline hex fallbacks keep the widget honest on a page
   that hasn't (e.g. a smoke harness).

   Placement is the CONSUMER's: the app mounts the launcher in the
   topbar (top-right chrome); tools mounts it fixed bottom-left,
   safe-area aware. Panel: 380px slide-in desktop; full sheet under
   640px (100dvh + visualViewport re-size handled in widget.js).

   Authored 2026-07-29 by 2-W2 (seat-2 builder spawn).

/* BL-318 polish 2026-07-29 (2-W3) — COMPOSER CLIPPING.
   Measured from source on the REAL app page (headless Chromium over
   app/index.html + css/app.css with body.pga-ready, viewport 1512x791):
   the panel ran `top:0; bottom:0` — the LAYOUT viewport — so the
   composer landed flush on the viewport edge (compose bottom ==
   innerHeight) inside the app's reserved bottom band, where .pga-bar
   sits. Every other app surface stops above that band
   (#map { bottom: var(--bar-band-h) }); this panel was the exception.
   Fix = the spec's 100dvh discipline at EVERY width (it was <640px
   only): the panel tracks the VISUAL viewport — mobile URL-bar
   collapse, on-screen keyboard, desktop pinch-zoom — instead of the
   layout one. widget.js publishes --fc-vvh from visualViewport on
   every surface; 100dvh is the no-JS fallback, 100vh the pre-dvh one. */
