Refactor public/style.css to semantic CSS custom properties under :root (light palette by default) and add a @media (prefers-color-scheme: dark) override block that flips background/foreground/accent/danger tokens to a soft near-black palette. The original --black/--white/--gray-*/--red literal tokens and the lone #fff5f5 floating literal are gone — every color now derives from a semantic token, so the dark override is the only place that re-declares them. Add <meta name="color-scheme" content="light dark"> to the shared layout <head> so the browser renders its UA backdrop, native scrollbars, and form-control popups in the user's preferred scheme before the stylesheet parses — this is what avoids a white flash on initial paint in dark mode. No toggle, no JS, no preference persistence — the page follows the OS setting directly via the media query. The 16px font-size rule on text-entry inputs is preserved (still asserted by tests/integration /style.test.ts).
