/* ─── Voice & Chat Widget — production styles ─────────────────────────
 *
 * Recreated from the design handoff in /chat design/. The widget runs
 * inside an iframe and fills its parent. Light and dark skins live on
 * `.widget[data-skin]` — set initially by app.js from prefers-color-
 * scheme and toggled by the in-widget sun/moon button.
 *
 * Fonts: Inter for UI, Fraunces for display (titles, "who" labels).
 * CSP blocks Google Fonts so we declare them first in the stack and
 * fall back to system fonts when not preloaded by the host page.
