   DM Sans, Literata, IBM Plex Mono: cabinet and the pages that still use them.
   Inter: public pages, onboarding and the four course tabs (body.app-course). One variable file per script carries both
   optical sizes (opsz 14–32) and weights 400–600, so Text and Display are not two downloads.
   Subsets (2026-10-14): latin 44 KB, cyrillic 19 KB, latin-ext 84 KB.
   Literata Logo: the four letters of the wordmark, so a public page does not pull the full Literata. */
