Wires tailwind.config.ts to every custom-property token in styles.css
(spacing, OKLCH colours, radii, z-index, sizing, durations) so Tailwind
utilities resolve to the same variables the vanilla CSS uses. Adds
ThemeContext/useTheme as a React port of theme.ts, keeping the same
localStorage keys and data-theme/data-palette attributes so it can run
alongside the vanilla shell.
Adds react, react-dom, zustand, tailwindcss, @tailwindcss/vite as a new
skeleton alongside the existing vanilla SPA. New src/index.tsx entry
point (unused until wired into index.html in a later issue); main.ts
stays the active entry.
