/* COGO calculator design system.

   SCOPED under .cogo: this sheet carries .container, .btn, .card and .hero, all
   of which the shared header and footer also use. The three traps the
   2026-08-24 port hit are all live here, so:

   1. cine.css pads .card by 30px, which is right for the site's content cards
      and wrong for these, which pad their own head and body. Hence .card{padding:0}.
   2. A body or html selector cannot match from inside the wrapper. There is no
      print block in this tool; if one is ever added, it goes ABOVE the wrapper.
   3. Base component rules (.card-head, .card-body, .fieldbox) are not in
      cine.css, so they are carried here, along with this tool's own layout.

   This tool does not print. Its outputs leave as a copied block, a downloaded
   CSV, or a screenshot of the plan. */

     These rows hold a different number of tiles per panel, and two of them change
     count at runtime. A fixed four-column grid orphaned "Area enclosed" alone with
     543px of dead space beside it. Grid auto-fit looked like the fix and is not:
     it only fills the row when the tile count happens to divide by the column
     count, so five tiles fit exactly at a 1440px window and orphan again at 1200.
     Flex wrap with a grow factor fills every row at every width, because the last
     row's tiles stretch to take what is left. */
