/* ==========================================================================
   Inbox assistant — admin UI
   --------------------------------------------------------------------------
   Hand-written, no build step, no framework, and NO JavaScript anywhere: the
   Content-Security-Policy on every response is script-src 'none'. Anything
   that looks interactive here is CSS only (:target, :focus-within, :checked).

   Brand orange #FF6200 is sampled from the AirGo wordmark. It is used for
   identity and for the single primary action on a page — never for status.
   Status has its own colours, because "the thing you click" and "the thing
   that is wrong" must never look the same.

   script-src 'none', so there is no JavaScript to open anything with. A
