/* relink.css [WP14] — the relink split view (CONTRACT.md §11).
 * Self-contained: does not depend on edit.css or plugin-host's injected
 * styles being loaded — every class here is its own (`vp-relink-*`). Colors
 * restyled to the "All Subjects" editorial brand (brand.css tokens), with a
 * literal fallback on every var() so this still renders correctly if ever
 * reached before brand.css loads. Genuine state colors (amber "unsaved",
 * green "free slot"/"success", the map's occupied/error red) stay their own
 * hue — those are functional signals, not brand chrome, and diluting them
 * into a single crimson would blur the meaning. */
