   SECTOR VIDEO-HERO LEGIBILITY — "reverse camouflage" + shadow floor
   The hero text over the scroll-scrubbed background video stays legible
   two ways: (1) a permanent text-shadow FLOOR so it never washes out on
   any frame, and (2) JS samples the video luminance behind the heading on
   each scroll tick and flips .cam-light / .cam-dark on .page-hero so the
   type colour inverts as the footage flows. If pixel-sampling isn't
   available (e.g. opened as a local file:// where the video canvas is
   tainted), it falls back to the light-on-dark floor, still fully legible.
