   IGNITE MY AI — site styles (v3: layout + motion pass)
   ------------------------------------------------------------
   On top of v2's editorial layout, v3 adds:
   · SIGNATURE — the "ignite fuse": a scroll-drawn ember line
   · scroll reveals (Jakub polish + Jhey craft, reduced-motion safe)
   · sticky-heading + threaded How-it-works (grid-break)
   · storytelling service-row hovers (number → arrow, underline wipe)
   · a whisper of warm grain for tactile depth
