/**
 * Preload a stylesheet via `<link rel="preload">` — a browser-only progressive
 * enhancement. Guard on RUNTIME DOM availability (`typeof document`), not the
 * build-time `import.meta.env.SSR` flag: the flag is only set in vite's SSR
 * build, so `!import.meta.env.SSR` was `true` (→ ran `document.createElement`)
 * in EVERY other non-browser context — plain Node, a worker, a non-vite SSR
 * host, a test without a DOM — throwing `ReferenceError: document is not
 * defined`. A capability check is correct everywhere: it runs exactly when a
 * document exists and is a safe no-op otherwise. (Fixes #141.)
