/*
 * site.css — THEMEABLE structural stylesheet (Phase-2 M0 token edition).
 *
 * This is the tokenized successor to the committed rbs-site/assets/site.css.
 * Every operator-changeable literal is consumed via `var(--token, fallback)`
 * where the FALLBACK is the committed default value — so:
 *   - with NO theme cell / the DEFAULT theme (which emits no :root), the
 *     computed styles are byte-for-byte the same look as the committed CSS
 *     (every var() resolves to its fallback);
 *   - a NON-default theme's injected `:root{…}` (emitted by layout.ts after
 *     this stylesheet's <link>) overrides only the tokens it changes.
 *
 * The :root here also publishes the default token values explicitly (so the
 * tokens are inspectable / overridable as a set), matching DEFAULT_THEME_TOKENS
 * in cartridges/site/brain/src/cell-types/theme.ts. The duplicated literals in
 * the var() fallbacks are intentional belt-and-braces: a token can be unset
 * (removed from :root) and the page still renders.
 *
 * DEPLOY NOTE: promoting this file to the LIVE rbs-site/assets/site.css is a
 * one-time deploy step (outside this worktree's golden masters). The HTML
 * golden-master gate is unaffected — render never rewrites assets, and the
 * default-theme HTML is byte-identical regardless of which site.css is served.
