/* ============================================================
   TSM AI Studio — proxy-injected theme overlay for LibreChat
   Non-destructive: overrides brand accent colors, background,
   input glow, and header surface. Tuned to be layout-safe.
   Full component redesign (custom selector / quick cards) needs
   the from-source build.
