/* ============================================================================
   nkda-fonts.css — the estate text-font axis.

   `data-nkda-font` on <html> selects the reading font: default | dyslexic |
   lexend | atkinson. Stamped by the appearance pre-paint, persisted with the
   theme in the same cookie/account preference.

   All binaries are SELF-HOSTED from this module's static/fonts/ (served at
   /fonts/) — no property makes a third-party font request. Licences (all SIL
   OFL 1.1): OpenDyslexic © The OpenDyslexic Project; Lexend © The Lexend
   Project Authors; Atkinson Hyperlegible © Braille Institute of America.

   Mechanism note (host contract): each block sets --bs-body-font-family AND
   applies it to body directly. The direct rule is load-bearing — an
   attribute-qualified `[data-nkda-font] body` (0,1,1) outweighs a channel's
   plain `body { font-family }` (0,0,1), so the choice wins without
   !important. A channel must not set a body font-family at all (retired-
   pattern register: body-font-family) — the estate default rides
   --bs-body-font-family instead.

   `font-display: swap` throughout: text renders in the fallback instantly.
