/* ============================================================
   v0.14 — HORIZONTAL-OVERFLOW HARDENING (2026-05-25)
   Root cause Sven 25.05.: <select> elements have intrinsic min-width
   derived from their widest <option> text. With display:grid (which
   defaults to min-width:auto on items), the row+form+pane chain refuses
   to shrink below that intrinsic width on narrow viewports. The fix is
   threefold: min-width:0 down the chain, max-width:100% on form fields,
   and a defensive `overflow-x: clip` on <html> as a last-line guard.
