/*
 * THE BRAND FACES WERE NAMED IN tokens.css FROM THE FIRST COMMIT AND NEVER
 * SHIPPED. `--font-heading` has always read "Source Serif 4", Georgia, … and
 * `--font-body` "Source Sans 3", -apple-system, … with no @font-face anywhere
 * in the project, so every page since Sprint 0 has rendered in Georgia and
 * Segoe UI. The fallbacks are good ones, which is exactly why nothing looked
 * broken — and why the guideline's claim that the banded layout's character is
 * carried "typographically, not structurally" was not true of the built site.
 *
 * SELF-HOSTED, per DESIGN.md §3 and §13. No Google Fonts stylesheet link: that
 * is a third-party request on every page, it leaks the visitor's address to
 * another operator before any consent is collected (Story 6.1), and it puts a
 * render-blocking round trip in front of first paint.
 *
 * NOTHING HERE BLOCKS FIRST PAINT (NFR4). `font-display: swap` renders the
 * fallback immediately and repaints when the face arrives, and there is
 * deliberately no <link rel="preload">: preloading would make these four files
 * compete with the stylesheet for the first connection, which is the opposite
 * of what swap is for.
 *
 * SUBSETS. `latin` and `latin-ext` only — DESIGN.md §3 asks for Latin plus
 * Latin-Extended-A. The `unicode-range` on each face is what makes the split
 * worth having: German umlauts and ß all live in U+0000-00FF, so a page of this
 * site's own content fetches only the `latin` files (28 KB + 120 KB) and the
 * browser never requests latin-ext at all.
 *
 * WEIGHT IS A RANGE, NOT A NUMBER, because both files are variable fonts.
 * Google's API serves ONE file for weight 400 and weight 600 — the same URL for
 * both — so declaring `font-weight: 600` here would name a static instance that
 * does not exist and every browser would render the variable default instead.
 * `200 900` is the wght axis each family actually carries, and the
 * `font-weight` on a heading or a button then selects within it.
 *
 * Licence: SIL Open Font License 1.1 — assets/fonts/OFL.txt, shipped alongside
 * the files as the licence requires. Source: Adobe, via Google Fonts v19/v14.
