/* ==========================================================================
   TOOL BLOCK START - exif-remover
   exifremover.css - EXIF Remover
   UnitConverterTool.com | Silo: Image Tools. Accent #4a90ff, hover #3a7fee.
   Built from tool-build.md sections 1, 3, 3c, 3d, 3e, 3f, 3g, 3h, 3h-cloud
   and 3i, ported from the exam-form-photo donor.

   DROPPED FROM THE DONOR, because this tool has none of them:
     - the whole crop stage, guide overlay, filmstrip and Cropper override block
     - the aspect lock, preset cards and the ink slider
     - the progress/size-compare pair is kept, because a 100 MB TIFF genuinely
       takes long enough to need a bar

   ADDED: the key/value metadata table. Two columns, sectioned by full-width
   colspan header rows that pick up the existing .uct-table th styling. No new
   class was invented for the group titles.

   THE TWO-COLUMN TABLE RULE (3g, amended 9 Aug 2026). Not a deviation:

     3 or more columns -> keep min-width: 480px and let .uct-table-wrap scroll.
                          The wrapper scrolling is the deliberate safety valve.
                          Assert the wrapper SCROLLS and the table is fully
                          reachable, not that it fits.
     exactly 2 columns -> drop the min-width, use table-layout: fixed, let it
                          FIT. Assert wrapper.scrollWidth <= clientWidth.

   This table is label-and-value, so it is the two-column case. Values are read
   top to bottom, and a page holding fifteen of these would otherwise demand a
   separate horizontal scroll gesture per table, losing content each time.
   The wrapper keeps overflow-x: auto as a backstop; it should never scroll.

   NOTE FOR THE NEXT BUILD: do NOT carry this table CSS to dpi-checker. Both of
   its tables are 3-plus columns, so they keep min-width: 480px and scroll.
