Browser-based feed selection layered on top of config/feeds.php: - manage.php (password + CSRF gated, session based): add subreddits (name / r/name / URL) and YouTube channels (@handle / UC id / URL, handle resolved to channel_id once, youtube.com only); enable/disable toggles; remove manual feeds; config feeds are hidden, not deleted. - New feeds are validated with one immediate fetch (bypassing the per-refresh host cap): HTTP 404 rejects the entry, 429 keeps it for a later refresh. YouTube labels adopt the real channel title. - feeds table gains origin (config|manual) and enabled columns, with a guarded ALTER migration for existing databases. - Only enabled feeds are refreshed and served: getItems/countItems filter by feed_url in enabled feeds, so deselected feeds' cached stories are hidden, not deleted; re-adding a URL re-enables it. - Dashboard header gets a Manage link; manage page styled with the existing design tokens; README documents the feature.
