Replace incorrect perceived-brightness formula in Stats progress bars
with proper WCAG relative luminance calculation, and convert type bar
colors to hex values for reliable contrast detection. Add light: variant
classes to status badges, yellow/purple text, and admin nav links across
17 files. Darken light-mode status-active token and text-tertiary/muted
tokens. Add aria-labels to admin filter selects and flex-wrap for mobile
overflow on AdminEvolutions.

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.

Set up pre-commit framework with ruff (backend) and ESLint/Prettier/tsc
(frontend) hooks to catch issues locally before CI. Auto-format all
frontend files with Prettier to comply with the new check.
