/* ---------- Shared guards + visibility utilities (promoted from page-local styles, 2026-09-06) ----------
   1) Grid tracks holding <input type="date"> / type="search" must be allowed to shrink on phones:
      those inputs have a wide min-content, so plain 1fr tracks overflow the card. All shared grids above
      now use minmax(0, 1fr); this also guards the field wrappers inside them.
   2) .only-phone / .until-desktop / .only-desktop: show controls in exactly one layout tier. */
