/* ==========================================================================
   Corvus Library additions to the Corvus design system v2.
   corvus.css is a byte-for-byte copy of the Hub's (the upstream) and is never
   edited here. This file loads after it and holds only what the Library adds.
   Never restyle a corvus.css class here; add a Library class instead.
   Every colour comes from a corvus.css token. Nothing here names a hue except
   the creator tokens in section 1, which are copied from Command.

   Sections
     1. Tokens: the eight creator colours corvus.css does not define
     2. Global fixes
     3. Admin: shared bits
     4. Admin: language chips (shared with the reader)
     5. Admin: pages, page editor, tracker, creators, bundles, activity
     6. Reader: the public reading page
     7. Reader: bundle
     8. Reader: link unavailable
   ========================================================================== */

/* --------------------------------------------------------------------------
   1. Creator tokens.

   corvus.css defines and binds six: Lucia, Lexie, Romy, Kayla, Cherry,
   Katherine. The other eight are copied unchanged from Command's command.css
   (which took Tyra from Studio and Sofia and Yumi from Socials), so a creator
   has one colour in every Corvus app. Anyone without a token keeps the grey
   dot: --creator falls back to --ink-3 in corvus.css. Never add a colour here
   that the design system (docs/Corvus_Design_System_v2.md, section 2.3) does
   not list.

   Keys: data-creator is the `ckey` filter of the creator RECORD's name
   (app/filters.py). A link with only a typed label and no creator record is
   given an empty key on purpose, and so the grey dot.
