/* Self-hosted webfonts for the ppsds decks.
 *
 * Loaded from index.html with a document-relative path (`./fonts/fonts.css`),
 * so it stays correct under `/talks/<slug>/` without relying on Vite's base
 * rewriting inside the bundled CSS.
 *
 * Both families are variable fonts (weight axis).  We ship the Latin and Greek
 * subsets separately: the deck uses `ε` in plain text (not only inside KaTeX),
 * and the Latin subset does not contain Greek glyphs.
 * Licences: SIL OFL 1.1 (see OFL-*.txt).
