   eSora Frequency — the eSora mark IS the experience.
   Editorial Paper system using ONLY the approved eSora tokens:
   Paper #F6F5F1, Ink #100F0D, rust-on-paper #B6481B (accents),
   rust-on-ink #D2602C (on-dark highlights), paper-on-rust
   #FFF7F0; secondary text uses the site's approved neutrals
   (#4A4A4F ink2 / #8A8A92 muted). No invented brown/orange shades.
   Fraunces for the daily thought, Geist for interface text,
   JetBrains Mono for technical labels and time.
   No navy, no glass, no orbs, no orbit graphics, no black circle.
