/*
 * Backwards-compatibility aliases.
 *
 * These map the old token names onto the semantic system in semantic.css so
 * components can migrate gradually. Nothing new should reference them — they
 * exist only so un-migrated call sites keep resolving. Delete entries as their
 * consumers move to the semantic tokens; the file goes away once it is empty.
 *
 * Kept separate from semantic.css so the core model reads as just inputs →
 * derivations. Must be imported after semantic.css (see tailwind.config.css).
