+- Cargo workspace (resolver 3) with all crates under `crates/*` picked up automatically.
+- `crates/01-hello` (package `hello`): minimal binary crate.
+- `crates/02-variables` (package `variables`): annotated showcase (comments in Czech) of working with variables in Rust: `let`/`mut`, shadowing, types and literals, overflow handling, casting, `const`/`static`, tuples/arrays/`Vec`, destructuring, deferred initialization, block/`if`/`match`/`loop` expressions, scope, move vs. copy, references, `&str` vs. `String`, `Option`/`if let` and `let-else`.
