The theme handoff encoded as CSS custom properties rather than a Tailwind config, since there is no Tailwind here. Palette, spacing, radii, shadows and motion follow it as written; docs/theme.md lists what differs and why. - Oswald vendored as a 21KB variable woff2, latin subset, no CDN. Its phantom weight 900 resolved to 700 — loading a weight you don't have is what made the brand render differently per platform - color-scheme: dark makes the native audio element fit the palette, which was the handoff's complaint about it - Songs are text cards rather than artwork tiles, because there is no artwork. The unreviewed state keeps its red-brown border and gains a badge, so it is never carried by colour alone - Nav is the three-column grid; the mobile menu is <details>, no JS - Flash messages became bottom-right toasts Favicon carried over from the Nuxt project.
