/**
 * Svelte context plumbing for the messages system.
 *
 * The context value is a **getter** `() => Messages`, not a snapshot. Storing
 * a getter lets the consumer's i18n library drive reactivity transparently:
 * they pass `messages={() => somethingReactive()}` to `<FlowDrop>`, the root
 * `$derived`s the merged tree, and `m()` re-reads it on every access. No
 * subscription, no store, no flowdrop-owned reactive primitive.
 *
 * Components rendered outside the root provider (Storybook stories, ad-hoc
 * mounts) silently fall back to `defaultMessages` rather than throwing — see
 * `getMessages()` below. Trade-off: a missing provider produces English
 * regardless of the consumer's locale, by design.
