/* BadgerMe — site styles
   No external requests: system fonts only, no analytics, no trackers.
   A privacy app shouldn't have a website that phones home.

   Colour discipline (the "identity ⊥ escalation" rule):
   - IDENTITY tokens (fur / bone / stripe / lines) are persistent and neutral.
   - ESCALATION tokens (cool → warm → hot) encode heat ONLY. They appear on the
     spine and on genuine escalation cues, never as general-purpose accents. */
