DB/API already supported arbitrary-depth replies via the self-referencing
parentId, but the UI only rendered top-level + one reply level — a
reply-to-a-reply was fetched but never shown. Rewrite CommentItem as a
recursive component keyed off a parentId->children map; visual indent
caps at 4 levels (Reddit-style flatten) but nesting itself is unbounded.

Wires dozens of components and server pages to next-intl instead of hardcoded
English text, and adds a lightweight getMessages/formatMessage helper for
server components (print pages, public recipe page, cook metadata) since
next-intl/server isn't wired into this app's routing. Backfills missing
en/fr message keys that existing code already referenced but fr.json lacked.
Follow/unfollow users. Recipe favorites. Threaded comments with emoji reactions.
Collections (public/private) with shared member invite. Activity feed.
Public profile pages at /u/[username].
