   --ti-brush-opacity-elevated, --ti-radius-control, --ti-radius-panel,

     matching the Portal's own light-mode buttons, which stay a
     metallic graphite tone rather than inverting to white (confirmed

/* WEB-HERO-SCREENSHOT-STYLING-INCONSISTENCY-001 (physical-QA rejection,
   2026-09-15): matching border/radius/background alone left the actual
   COMPOSITION wrong -- `.hero-grid`'s own column track
   (`minmax(310px,.65fr)`) stretched this container to fill the whole
   grid cell (grid items default to `justify-self: stretch`), while the
   image inside stayed capped at a much narrower 280px -- a "frame inside
   a frame" with large empty gutters on both sides, nothing like the
   gallery's own tight image-to-card ratio. Fix: `justify-self: center`
   stops the container from stretching across its full grid track, and
   `max-width` sizes it to closely wrap its own image content (320px
   image + 2x20px padding + 2x1px border = 362px; 380px leaves a small,
   deliberate margin) -- so the container's size is now driven BY the
   image, exactly like `.product-card` is sized by its own image, not by
   an independent grid-track width. The image itself is also sized up
   slightly (280px -> 320px) to give the hero a bit more visual weight
   than a gallery card, matching "same system, different scale" rather
   than an identical size. */
