   Palette drawn from assets/profile-icon.png:
   cream page, deep-teal ink, muted-teal accent.

   Type: PP Editorial New (Regular) is the intended primary display
   face but is a paid Pangram Pangram release, so it isn't loaded here.
   Instrument Serif stands in for it — a free, purpose-built lookalike
   (thin, high-contrast editorial serif, Regular + Italic only, so
   there's no synthetic-bold risk). Body/UI copy runs on Instrument
   Sans rather than a generic system font like Inter — it's the sister
   sans released by the same foundry specifically to pair with
   Instrument Serif, so headings and everything around them read as
   one considered system instead of two unrelated typefaces.
