   Until now the "Book Paper" system relied on system font stacks: the
   prose serif was Charter, which ships ONLY on Apple platforms, so
   Windows and Android readers fell back to Georgia/Roboto and never saw
   the designed look. These three latin-subset VARIABLE woff2 files give
   every platform the same typography:

     - Literata (roman + italic): Google's long-form e-book serif with
       an optical-size axis (opsz 7..72). Carries all textbook prose.
       ~110 KB + ~113 KB.
     - Inter (roman): the UI sans the typography.css stack has always
       named but never loaded. Carries buttons, nav, labels. ~73 KB.

   Loading strategy: font-display swap (brief system-font flash on the
   very first uncached visit, same as the Fraunces precedent in
   welcome-v2-emphasis.css); the roman files are <link rel=preload>'d
   in index.html and precached by sw.js, so it is a one-time event.
   unicode-range keeps non-latin pages from downloading them at all.
   Licenses: OFL.txt alongside each family in vendor/fonts/.
