- SvelteKit + Svelte 5 (runes mode enabled)
- Tailwind CSS v4 via @tailwindcss/vite plugin
- TypeScript strict mode
- ESLint 9 flat config with svelte and typescript-eslint plugins
- Prettier with svelte plugin

 - Use Glob to find all source files (`src/**/*.ts`, `src/**/*.tsx`, `src/**/*.css`, `src/**/*.vue`, `src/**/*.svelte`, etc.)
 - Use Grep to find patterns of concern (see checklist below)
