/* Interaction identity (Phase I-3): pointer pipeline mount — "flashlight
   照車庫" full-page spotlight, wider radius/stronger intensity than
   Portal's dock (320px/8% vs 240px/6%, per the brief's Cars list).
   Equivalent to motion.css's .hx-spotlight, mounted via direct selector
   instead of the class for both halves:
   - `.car-panel[data-hx-pointer]` — I-3's allowed HTML edit for cars.html
     is the data-hx-pointer attribute only, added to the five (static,
     never JS-replaced) <section class="car-panel"> elements. Uses ::after
     (no existing user on this element).
   - `.media-grid figure` — these six figures ARE replaced wholesale by
     js/cars/main.js's innerHTML swap from /data/cars.json, which this
     phase cannot touch (outside I-3's allowed-files list), so there is no
     HTML attribute to select on here. js/lib/pointer-fx.js's own
     SELECTOR constant carries the identical `.media-grid figure`
     structural fallback for this exact reason — see its header comment.
     Uses ::before instead of ::after: every figure already carries
     hx-sheen, which owns ::after for its hover sweep (motion.css) —
     ::before keeps both effects layered instead of one clobbering the
     other's pseudo-element.
   No tilt here — the brief's Cars list is spotlight-only. Positioning
   context (`position: relative`) is scoped inside the same media gate as
   the pseudo-element itself, not left unconditional: touch and reduced-
   motion contexts get zero side effects from this mount, not even an
   invisible one. */
