   TESTKAV SKILLS — HOME HERO v9 (first section of the landing page)
   Dark stage, brand yellow as the light. Copy: a question whose skill word
   rotates, the slogan, the search. Visual: a live gauge whose needle and score
   answer the question for each skill in turn.
   Always dark (both themes); site header/footer untouched; scoped to .tkh.
