/* Docs assistant — floating chat widget for the gated microsite pages.
 *
 * A floating chat widget built in plain CSS:
 *   - the launcher is a pure-CSS orb (no assets)
 *   - bubble geometry and the composer pill follow a standard chat layout
 *     (no external assets)
 * Design note: rather than docking the chat as a right-hand
 * column of an app shell, this is a floating
 * panel anchored to the same bottom-right corner as the launcher.
 *
 * Every colour is an existing --hx-* / --glass-* token from css/semantic-tokens.css,
 * which each gated page already loads. No new tokens, and the light-mode block in
 * that file re-points them, so the widget follows the page theme for free.
