//! Curated theme pack (#1461): generated TOML files under `pack/`, embedded
//! into the binary and served as built-in themes alongside the hand-built
//! presets in `render::presets`.
//!
//! The pack is built once through the EXISTING user-theme validator
//! (`user_themes::build_theme`), so embedded themes are held to exactly the
//! standard a `~/.opencrabs/themes/` drop-in file is: all 43 keys, valid
//! hex, 2.5:1 WCAG contrast floor on the 8 readability pairs. Regeneration
//! instructions live in `pack/README.md`; per-theme provenance in each
//! generated file's `# source:` header.
//!
//! Two invariants keep the wiring safe:
//! - `build_theme` rejects stems colliding with `presets::by_name`, and
//!   `by_name` consults this pack. During pack initialization
//!   `PACK_THEMES.get()` is `None` (`OnceLock::get` never forces), so the
//!   collision check sees the pack's own names as not-yet-built-in and
//!   cannot re-enter the initializer. This is why the pack is an
//!   `OnceLock` + non-forcing `themes_if_built()`, NOT a `LazyLock`, and
//!   why `presets::by_name` must never call the forcing `built_ins()`.
//! - `src/tests/theme_pack_test.rs` proves every embedded file passes
//!   `build_theme`, so the runtime skip branch below is unreachable; a
//!   corrupted embed degrades to fewer themes, never a panic in the TUI.
