/* Bot Match tool-specific styles.
   The APP (app.html) wears the house shell: brand-base + brand-bot-match +
   shell.css own its frame; only chat and persona pieces live here.
   The LANDING (index.html) is the marketing front door and carries its own
   look, scoped under body.landing so it never fights the shell. */
