# this project

A SvelteKit (Svelte 5) + Tailwind CSS v4 project.

Stack: SvelteKit (Svelte 5), Tailwind CSS v4.

## Commands

- Dev server: `npm run dev`
- Build: `npm run build`
- Type check: `npm run check`

## How to work in this repo

- Read the relevant files before editing. Follow the patterns already in the codebase over these generic rules.
- Make the smallest change that solves the task. Do not refactor or reformat unrelated code.
- Before saying a task is done, run the type-check, lint and tests listed under Commands and fix what you broke.
- If requirements are ambiguous, ask one clear question instead of guessing.
- Never commit secrets, API keys or `.env` files. Use env vars and keep `.env.example` up to date.
- Do not add a new dependency when the standard library or an existing dependency already covers it.
- Ask before adding, removing or upgrading any dependency.
- Ask before changing database schemas, auth, payments or CI configuration.
- Never delete files, drop data or run destructive commands (`rm -rf`, `git push --force`, `DROP TABLE`) without explicit approval.
- Keep each change under ~200 changed lines where possible; split larger work into steps.

# SvelteKit (Svelte 5)

- Use Svelte 5 runes: `$state`, `$derived`, `$effect`, `$props`. Do not use legacy `export let` or `$:` syntax in new code.
- Prefer `$derived` over `$effect` for computed values. Use `$effect` only for real side effects.
- Load data in `+page.server.ts` / `+layout.server.ts` `load` functions, not in `onMount`.
- Handle form submissions with form actions and `use:enhance`.
- Read secrets from `$env/static/private` or `$env/dynamic/private`, only in server files.
- Use `error()` and `redirect()` from `@sveltejs/kit` for control flow in load functions and actions.

# Tailwind CSS v4

- Tailwind v4 is configured in CSS: `@import "tailwindcss";` plus `@theme { ... }` for design tokens. Do not create a `tailwind.config.js` unless the project already has one.
- Use theme tokens (colors, spacing) instead of arbitrary values like `w-[37px]`.
- Build responsive layouts mobile-first with `sm:`, `md:`, `lg:` prefixes.
- Extract repeated class lists into components, not `@apply` chains.
- Support dark mode with the `dark:` variant when the project uses it.
