/* ==========================================================================
   LUNA — LOOP's AI assistant. Self-hosted, zero external hosts, zero CDN.
   Every colour falls back to a literal, so she renders correctly even when
   mounted on a page that does not define the 2026 Waucht tokens.

   Visual language deliberately matches Luna's EXISTING surface (her cockpit
   HUD): deep navy, cream text, ember accent used only on active states. She
   is not a grey helpdesk bubble — she is the product, on the page.
