/* Ember in public — the homepage entry and the Talk to Ember panel
 * (forgeos-ember-public.js; the face is forgeos-guide's).
 *
 * The site is navy and indigo; Ember is the one warm thing on it. The warmth
 * is spent in two places only -- the face, and a thin ember edge on what
 * Ember says -- so the panel still reads as part of the site. Day surfaces
 * come from the platform tokens, so light, dark and the theme toggle all hold.
 * No inline styles: the page is served under style-src 'self'. */
