Readers can now choose which quick-access lanes sit above the feed; "Today" stays pinned. The pool (goodnews/lanes.py, served at /api/lanes) is one source of truth over three lane kinds the feed already renders: moods, primary topics, and high-volume Discovery tags. Selection lives in the existing prefs blob (localStorage + /api/prefs sync); the filter parser ignores the new `lanes` field, so it rides along harmlessly. Default = today's moods, unchanged. Food/Space stay grouping tags rather than primary topics (per review): `space` already existed; added `food` to the Mind & Craft family so the classifier assigns it, and seeded the Food lane by re-tagging the two food sources.
