+/**
+ * Recipes — the heavyweight tier of HyperFrames user memory.
+ *
+ * A recipe is the full confirmed bundle for one video type: the frozen design
+ * spec (`frame.md`), the storyboard skeleton (structure with the content
+ * blanked), and the confirmed brief values — frozen after the run's final
+ * approval, reused to start the next video of the same type from everything
+ * already approved.
+ *
+ * Storage is **named folders**, not content-addressed cache entries: a recipe
+ * is an evolving bundle with a `version`, so re-freezing the same name bumps
+ * the version and archives the old folder as `<name>@v<N>`. Two tiers, same
+ * split as everything else in media-use: project `.media/recipes/<name>/`
+ * (committed) and user `~/.media/recipes/<name>/` (a freeze is already a
+ * confirmed bundle, so it promotes immediately — no two-project rule here).
