/*
 * The website chat's look (docs/site-chat.md). Everything a site may want to
 * change is a variable on .rc; set them in the site's own stylesheet, e.g.
 *
 *   .rc { --rc-accent: #0b6e4f; --rc-radius: 6px; }
 *
 * The defaults take the site's own design tokens where it has them: first our
 * own sites' (--color-accent, --color-text, --font-sans, --radius-md …, the
 * alterview.dev network), then a block theme's (--wp--preset--*), then calm
 * neutrals. Every rule below sets its own font, weight, colour and alignment
 * in longhand with .rc in front, so a theme's label, heading and button rules
 * cannot leak in (2026-10-08: they did on alterview.nl).
