/*
 * SoundLabs: shared site chrome on this page (nav, promo strip, footer, shared upgrade modal).
 *
 * The old css/soundlabs.css styled the shared chrome (dark #0D0C1D nav, system font, button look).
 * Those rules are ported here verbatim so the nav, footer and upgrade modal render exactly as before
 * (verified with before/after pixel diffs, docs/11-frontend-foundation-report.md), but every global
 * rule is now fenced away from the app (.sl-app, .sl-layer, .sl-seo), so nothing leaks into SoundLabs
 * components and nothing in the app depends on these rules. Do not add app styles here.
