/*
 * chat.eaon.dev: Eaon's Chat in a browser.
 *
 * The tokens are the desktop app's (src/renderer/src/styles/tokens.css) with
 * the Cobalt theme: every surface, border and text tone is mixed from --bg,
 * --fg and --contrast, so the web chat re-tones exactly like the app does.
 * The layout follows the desktop Chat tab: a floating sidebar panel, one
 * centred conversation column, steps folded into a summary row, and the
 * composer with + at one end, send at the other, and what Eaon may do and
 * the model under it. On phones the sidebar becomes a drawer.
