Run both `cargo check` commands and the tests after any change. They don't catch hydration errors, so after changing a view also load the page in a browser with a full reload (the browser caches the old WASM otherwise) and check the console; a plain `cargo check` / `cargo test` (no features) checks neither side properly.
Unit tests are `#[cfg(test)] mod tests` at the bottom of the file they test (`#[cfg(all(test, feature = "ssr"))]` for ssr-only code). They cover pure logic only — parsing, validation, paging, slot merging, mail templates, config. Nothing touches the database, so server functions, permissions and SQL are untested. Add tests for new pure logic; keep them free of DB and network.

- Code, comments, identifiers, log messages and commit messages are in English. UI strings are English keys translated at runtime (see `.claude/rules/frontend.md`).
- Commit messages are always written in English, even when the conversation is in Czech: short past-tense sentences ending with a period, e.g. "Added setting for closing days."
- The project has no rustfmt config and the code is not rustfmt-formatted. Don't run `cargo fmt` over existing files; match the surrounding style and keep diffs limited to what you changed.
- Leptos is 0.6 — use the 0.6 API (`create_signal`, `create_resource`, `create_server_action`, `#[component]` returning `impl IntoView`), not 0.7/0.8 (`signal()`, `Resource::new`, …).
- `wasm-bindgen` is pinned to `=0.2.100`; it must match the wasm-bindgen version of the installed cargo-leptos. Don't bump it on its own.
- Leptos is 0.8 — use the 0.8 API (`use leptos::prelude::*`, `signal()`, `RwSignal::new`, `Resource::new_blocking`, `ServerAction::<T>::new()`), not the 0.6 `create_*` functions.
- `wasm-bindgen` is pinned to an exact version in `Cargo.toml`. The `wasm-bindgen` CLI that cargo-leptos runs must be exactly the same version (`cargo install -f wasm-bindgen-cli --version <same>`), otherwise the front-end build fails with a schema version mismatch. Leptos 0.8 needs at least 0.2.108. Change the pin and the CLI together, never one of them.
- `#![recursion_limit = "512"]` at the top of `src/lib.rs` and `src/main.rs` is required: without it the release build fails with "queries overflow the depth limit".
- `.cargo/config.toml` selects the `getrandom` backend for the WASM target (needed by the captcha's proof of work). `getrandom` and `uuid` have their `js` features enabled in `Cargo.toml` for the same reason; don't remove them.
- Version lives in `Cargo.toml` and is shown in the page footer.
Detailed rules are in `.claude/rules/`: `backend.md`, `frontend.md`, `database.md`.
