/* Agent Desk tokens. One visual language shared with the Ridley personal desk:
   Bot Doctor's restrained terminal feel, IBM Plex type, thin rules.
   Appearance is a per-user setting (Settings > Appearance: Light, Dark or System). It is saved on the
   signed-in account and resolved to html[data-theme="light"|"dark"] before paint (theme-boot.js, shell.js).
   It changes only that person's view. Both sets use the same token names; components only read tokens.
   Fonts are self-hosted IBM Plex (OFL, see assets/fonts). */
