   Tharwa Project Switcher — overlay stylesheet
   ---------------------------------------------------------------------
   ALL selectors are prefixed ".tsw-" and everything lives inside the
   #tsw-root container. Zero global leakage: no bare-tag selectors, no
   resets applied to the host app. The overlay is position:fixed at an
   extreme z-index so it NEVER causes layout shift on the underlying SPA.
   Visual language per SWITCHER-SPEC.md.
