/* tokens.css — the Starforge visual layer (the "skin").
 *
 * THE SWAPPABLE LAYER: a future reframe edits THIS file (and component CSS that
 * references these variables) — not the structure or logic. Grounded in the
 * Session-4 Prime-reframe language (mockups/starforge-core-session4/forge.css):
 * cosmic / stellar / strategic-industrial. NEVER medieval, NEVER nautical.
 *
 * Anything visual a component needs should resolve to a var() declared here, so
 * the whole product can be reskinned by replacing this token set.
