/* ch268 (boss phone 368px: "grid cells stick out past the marquee, to the right, cells look too big"):
   with plain 1fr the automatic minimum (min-width:auto, amplified by aspect-ratio cross-size transfer in
   Chromium) floors every track at 103.17px > the 99px available -> grid scrollWidth 326 vs clientWidth 313,
   right column overran the board frame. minmax(0,1fr) + min-width:0 pin equal shrinking tracks;
   measured: tracks 98.86px, scrollWidth==clientWidth, all cells fit, no text clipped, no font-size touched.
   ch270 (boss phone 368x798: "middle open-box cell is too long, sticking out"): same story on the other axis —
   the center cell's content (label+value+button ≈ 103.17px min height) floored row 2 at 103.17px while the
   aspect-ratio squares refused to stretch, so the open cell hung 4.31px below its neighbours (bottom 343.17
   vs 338.86). Fix: rows are pinned equal too (minmax(0,1fr)) and the grid itself is square (aspect-ratio 1/1),
   while the center content is slimmed (padding 6→4, value line-height 1.1→1, button padding 6/4→5/3) to fit
   the 98.86px square; overflow:hidden on cells is the last-resort guard so content can never push a cell out
   of the formation again. Measured after: rows 98.8571x3, every cell 98.86x98.86, center bottom==338.86. */
