New per-user digestFrequency (hourly default | daily | off) on the
profile and in the settings UI. A scheduler job (15 min cadence) mails a
user once their oldest unread, unmailed notification exceeds the cadence
window: one localized mail per batch, grouped per pond then per page
with actor names and change/comment counts, enqueued through the mail
outbox. Sending marks the batch mailed — never read — and re-checks page
read permission per entry at send time; entries the user can no longer
read are dropped from the mail but still marked handled, so revoked
content cannot queue forever. Every mail carries a signed, single-purpose
unsubscribe link: it only flips the setting to off, renders a session-free
confirmation page, and sets no cookie.

New notifications table (payload denormalized for join-free rendering;
mailed_at already prepares the #95 digests). Generation fans page events
out to page and pond watchers, excluding the actors, and re-checks page
read permission per watcher at delivery time — a revoked watcher gets
nothing. Sources: named version snapshots (api), new comments (api), and
the collab server's automatic session-close snapshots — announced over a
new pg NOTIFY channel (the reverse of the established api→collab bus)
consumed by a dedicated LISTEN client in the api, since the collab server
has no permission resolution of its own. API: paginated list (unread
first via nulls-first ordering), mark read, mark all read. UI: bell with
unread badge in the top bar (30 s polling, no push in v1) and a dropdown
whose entries navigate and mark themselves read; comment notifications
deep-link with ?comments=1, which now opens the comments panel on load.
