/* 06-controls.css: index.html@cd3fd3f lines 297-444 (global sections, mesh-mode options, toggles, FIRST .export-btn block).
   The first .export-btn block (lines 425-444) stays here: it supplies width: 100%,
   which the second block in 11-export.css (lines 824-843) does not override. Do not merge them.
   06 T4a (06 3.4, 3.5): role tokens. The section-title bar, the selected mesh-mode border and radio dot and the
   toggle's on-track are Signal Red (--color-accent) on opaque surfaces of at most #161616, never on a tint. The
   toggle keeps its geometry: its off ring is an inset shadow, so the box size does not change. The first .export-btn
   block is the neutral base (no gradient, no lift); .export-btn--primary is the one Pivot Gold element of the layout
   (#export-zip, R-B5), with a Morph Black inner ring on hover.
   Slice of the original <style>, rewritten to role tokens (css-slices.mjs --report-only lists the difference, 07 S7);
   link order = file number. Do not reorder rules across files. */
