   DΛREΛKT_ ATOM — ui.chrome.tabs
   The welded tab strip (.gns-oc__tabs) for the cockpit subnav slot, and the
   in-ctl segmented group (.gns-oc__segs). The strip is ported rule-for-rule
   from the byte-identical ARC / SEAL private copies, which are the canonical
   shape; SHIELD's chamfered variant flattens onto this on alignment.
