/* ---------------------------------------------------------------------------
   Design notes

   Subject: a bench instrument for watching cryptographic ceremonies, used by
   one person at 11pm who needs to read base64url without squinting.

   Palette is a cool instrument bezel. Colour is not decoration here — cyan
   means a check passed and the guards are armed; amber means a safety guard
   has been deliberately switched off; rose means verification failed. If the
   page is amber anywhere, you are running an unsafe configuration on purpose.

   Type: IBM Plex Sans for prose, IBM Plex Mono for anything that is literally
   fixed-width data (credential IDs, AAGUIDs, JSON). Monospace is functional
   here, not stylistic.
