/// Macro to create all the mutable locals and a `DrawCtx` for test rendering.
/// Expands to variable bindings in the caller's scope so borrows stay valid.
///
/// Usage:
///   `make_draw_ctx!(ctx);`                          — defaults (NORMAL theme, ground floor)
///   `make_draw_ctx!(ctx, theme: &CYBERPUNK);`       — custom theme
///   `make_draw_ctx!(ctx, floor_seed: 42);`          — custom floor seed
///   `make_draw_ctx!(ctx, floor_info: Some((1,2)));`  — custom floor info
///   `make_draw_ctx!(ctx, theme: t, floor_seed: 6);` — combine overrides
