 * Base + chrome. Tokens live in 00-tokens.css; components that carry a measurement live in
 * 40-primitives.css onward.
 *
 * This file is the kit's Terminal sheet, RETINTED rather than rewritten: the shapes (.container,
 * .section, .card, .btn, .field, .nav, .flash) are sound and the auth and research pages already
 * use them. What changed is the ground. The kit was warm-dark with an amber accent; Stalewatch is
 * a light page with dark data panels and a cyan accent, so every var() was remapped onto the new
 * token set and the radii collapsed to --r: 0.
 *
 * Rules whose job is to display a NUMBER do not belong here. They belong in the numbered files
 * above, written against the semantic aliases so they are correct on both grounds.
