/* ===========================================================================
   Quest Vision AOI — dark navy theme, aligned with Quest Admin / Web.

   One palette, one type scale, one set of radii and control heights. Every
   surface in this file is a token; there are no ad-hoc light backgrounds left,
   because a single `#fff` or `#f8fafc` on a dark page reads as a hole punched
   through the screen.

   Photographs are the exception on purpose: crops, thumbnails and reference
   images carry **no filter, no blend mode and no opacity**. Their backdrop is a
   dark neutral so a `contain`-fitted image does not sit in a glaring box, but
   the pixels themselves are shown exactly as captured — this is an inspection
   tool, and tinting the evidence would be a defect, not a style.

   390px: let content shrink and wrap, never clip it.

   Measured in a real browser at 390×844: the queue was 390px wide and the review
   page was 966px. Three things were widening it, and none of them was the table —
   a table scrolling inside itself is fine.

   1. A grid or flex item defaults to `min-width: auto`, which is its *content*
      width. One 64-character path or SHA-256 inside a `minmax(300px, 1fr)` track
      therefore pushes the track past the viewport no matter how well the text
      could have wrapped. `min-width: 0` is what lets the wrapping below work.
   2. Hashes, ids, paths and filenames have no break opportunity. `overflow-wrap`
      is inherited, so one declaration on the page container covers every one of
      them without listing elements that will change.
   3. A file input and a `select` carry an intrinsic width of their own.

   What is deliberately *not* here: `overflow-x: hidden` on a page container. It
   would make the measurement look right while cutting evidence off the side of the
   screen, which is worse than the bug. --------------------------------------- */

   `max-width: 430px` query let the desktop page grow to 1519.

   The container is a block, not the table: `overflow` is not reliably honoured on a
   `display: table` box. `min-width: 0` keeps it shrinkable if it is ever placed in a flex
   or grid parent, and the focus ring is visible because `tabindex="0"` makes this a real
