/* Gate — "Jump to system" switcher (2026-09-30)
   ================================================
   One stylesheet for every app's modal. Colours come from the host app's CLU
   tokens (house rule 6) through a fallback chain, because each app names them
   differently: CLU/Libby/DeadDrop/Homebase use --bg-card/--text-primary,
   TransTrack --surface/--text, iMail/Cloudy --bg-card/--text, the Army
   --bg-elevated/--text-primary. The last value in each chain is the CLU dark
   palette, overridden below for light mode, so an app with none of these names
   still gets a readable modal in both themes.

   Light mode is whatever the host signals: html[data-theme="light"] (CLU apps,
   Cloudy, iMail, Homebase, the Project Index) or html[data-bs-theme="light"]
   (filerecon, Bootstrap). Everything is scoped under .sysw so nothing here
   leaks into the host page; the only host-facing rule is .sys-switch. */

/* Specificity (0,0,1) on purpose: beats a bare `a { color }` in the host app
   (so an <h1><a class="sys-switch"> keeps the heading colour) but LOSES to any
   classed brand rule (.sidebar-logo, .sidebar-brand, .topbar .brand …), so
   an app's own brand styling is untouched. */
