      description: 'Toggle a reaction on a post or comment.


        Exactly one of ``post_id`` or ``comment_id`` must be supplied —

        both empty or both set both raise 400 ``INVALID_INPUT``. The

        emoji slug must be one of ``ALLOWED_REACTIONS`` (defined in

        ``app/models/reaction.py``); arbitrary unicode emoji are rejected

        so the reactions UI stays curated.


        Idempotent toggle semantics: if the (user, target, emoji) row

        already exists it''s deleted (reaction removed). Otherwise it''s

        created and a ``post_reaction`` notification fires for the

        content author + a ``reaction.added`` webhook event fans out.

        Removals never fire notifications.


        Side effects on add: post-detail HTML cache invalidated for the

        affected post id (so the reactions bar redraws on the next

        visitor). For comment reactions the parent post id is used.


        Rate-limited 120 toggles per minute per user under the

        ``reaction`` bucket. Returns the full ``ReactionSummary`` for the

        target so the client can re-render without a follow-up GET.'

      description: 'List the people who reacted with a specific emoji.


        Used by the "Who reacted?" popover on post + comment pages.

        Newest reactions first, capped at 20 entries — there''s no

        pagination, the UI doesn''t need it.


        Returns ``{"emoji": "", "users": [{display_name, username}]}``.

        If neither ``post_id`` nor ``comment_id`` is supplied the

        response is ``{"users": []}`` rather than an error — the popover

        can fail-open without crashing. Auth not required; no rate

        limit (read-only).'
