/*
 * plc-tokens.css — the ONE alias layer between themes and domain components.
 *
 * Components in docs/wc/ read only --plc-* tokens. Themes (daisyUI 4, daisyUI 5,
 * or the studio's own --bg-* / --state-* blocks) are mapped here, once.
 * Adding a theme never touches a component; renaming a daisyUI token touches
 * only this file.
 *
 * Resolution order per token: studio override -> daisyUI 5 -> daisyUI 4 -> literal.
 * daisyUI 4 stores raw "L C H" triplets (--su: 0.6 0.2 150), hence oklch(var(--su)).
 *
 * Declared on [data-theme] too, so a themed subtree recomputes the aliases
 * (custom properties inherit their *computed* value from where they are declared).
