/*
 * frame, the chrome hairline frame. Unforged house identity 3.0.0 Broadside, 2026-08-22. Owner: Andreas.
 *
 * The only chrome geometry in the system (tokens chrome.frame): --u-chrome-frame, the ten stop
 * gradient measured off the mark, as border-image on a line.hairline transparent border, 96
 * degrees, paper only. A bounded panel, a card edge, a plate rule. Never a background, never a
 * button, never a band, never under type, and a mark never sits inside it (logo-usage.md section
 * 5). On the flood a frame takes rule.flood, because the flood already carries the chrome mark and
 * a second chrome object on it is a fill by accumulation: the rule is written here so a misuse
 * degrades to the hairline instead of painting chrome on ink. Padding is space.block, the padding
 * of a bounded field; --tight is one line box.
