Implement theme switching via sun/moon toggle in nav bar. Dark
remains the default; light mode overrides surface, text, border,
accent, and status color tokens. Preference persists in localStorage
and falls back to prefers-color-scheme. An inline script in
index.html prevents flash of wrong theme on load.
Define a Tailwind v4 @custom-variant for light mode and update all
badge components (encounter method, rule, condition) to use
light:bg-{color}-100 / light:text-{color}-700 for readable contrast
on light surfaces.

Replace Vite defaults with Nuzlocke Tracker branding: custom pokeball-
skull favicon (SVG + PNG + ICO), page title, meta description, Open
Graph tags, theme-color, web manifest, and package.json name.
