/* Master Context Strip v0 — #5034. BROWSER half.

   ⚠ TWIN of ~/spotsheet-helper/ui/master-context-strip.css. Byte-identical apart from
   this header and the two desktop-only blocks in the middle of the file — the
   #3977 impact confirm and the #3975 deleted-marker resolve cover — which live
   on the rig because only the rig writes markers. Change one, change the other
   in the same pass: "same field order, labels, iconography, clock typography
   and state colors across all modes" is the founder rule the strip exists to
   satisfy.

   #5695 reconciled the pair after a 220-line drift. What keeps them in step
   now is packaging/qa/verify-mcs-twin.sh (helper repo), not this comment.

   Uses tokens.css ONLY — no local palette. */

   The old strip was dropped into the 44px top bar with its panel background
   stripped (`.ss-topbar-mcs .mcs { background:transparent; padding:0 }`) and
   nothing put back, so the "pill" was naked text with a 9px --fg-faint chevron.
   It had no boundary, no hit area you could see, and no hover. This gives it a
   body without raising its voice: it must still sit UNDER the timecode in the
   visual hierarchy (#5301 — the master readout is the only live clock).

   Field order is unchanged from #5034 — PROJECT · VERSION · SESSION · TIMECODE
   — so the desktop twin keeps the contract. What changes is that the two
   subordinate fields stop competing with each other. */
