/**
 * assets/css/fonts.css
 *
 * Self-hosted webfonts + base typography.
 * Class C §2/§3: fonts are bundled locally — no external font CDN request,
 * no data leaves the visitor's browser to a third party on page load.
 *
 * FONT STACK
 * ----------
 * Primary: Google Sans Flex — two variable-font subsets (65 KB + 29 KB):
 *   google-sans-flex-body.woff2    — wdth=100, wght 300-700 variable, latin+latin-ext
 *   google-sans-flex-heading.woff2 — wdth=120, wght=700 static,       latin+latin-ext
 * Both generated via fontTools.varLib.instancer from the full variable TTF source.
 * No unicode-range splitting needed — each file covers all required codepoints.
 * Fallback: Inter (loads if Google Sans Flex fails; visually near-identical).
 * System fallback: standard sans stack (instant render before fonts load).
 *
 * WIDTH AXIS NOTE
 * --------------
 * The Figma headings use wdth=120 (expanded). The heading file is pinned there
 * and registered as 'Google Sans Flex Expanded', routed via --font-sans-expanded.
 * Body text uses the body file (wdth=100) via --font-sans; CSS font-weight values
 * 300/400/600/700 are interpolated from the wght axis at runtime — no separate
 * file per weight required.
 *
 * font-display: swap — text shows immediately in the fallback font, then swaps
 * to Google Sans Flex when it loads. No invisible-text flash (FOIT).
 *
 * @package AICenterwp
 * @since   1.0.2
