/* ============================================================
   Wordmark — "abracade", graduated fade (brand/abracade.json › wordmark).
   One word, one ink. `abra` is a graduated-opacity prefix (letters climbing
   faint → full) that hands off into a solid `cade`; the word appears to
   condense out of the air. Default is the solid ramp used in UI chrome
   (nav scale); `.wm--display` adds the hollow-outline hero treatment.
   Always --ab-ink — the accent never touches the wordmark.
