/*
 * site.css — what a multi-page site needs and a single demo page did not.
 *
 * Everything here obeys the rules `base.css` already establishes, because
 * those came from the audited design and `_doc/22`:
 *
 *   no box-shadow, ever      separation is background colour plus a 1px border
 *   radii 4 / 8 / 12         input, button, card. Nothing else.
 *   one type family          Inter, with Georgia italic for a single accented
 *                            word in a heading — `_doc/22` allows one per line
 *   no gradients             there is nothing to look at except the content
 *   tokens only              a raw hex here is a bug unless it is a tint of an
 *                            existing token that has no variable yet
 *
 * The demo is one page with a dark hero, so its header is dark unconditionally.
 * That carries over on purpose: the header is the brand bar and it looks the
 * same on every page, rather than changing identity between the home page and
 * an article.

 *   panels            every section's .container becomes a translucent island
 *                     floating over the world: 1px light border, no shadow,

 *   dark palette      the light-surface components (features, compare, stats,
 *                     notes, code, footer) restated in the ink palette
 *
 * Inner pages (guides, blog, legal) stay light on purpose: long-form reading
