The "wander" layer for the multi-tag model, sitting beneath the brief: - Cards show up to 3 tappable grouping pills (the article's tags), falling back to the primary topic for articles the re-tag hasn't reached. Tap a pill → that tag's lane. Tags read as little doorways, not metadata confetti. - New tag-lane view (select 'tag:<slug>' → /api/feed?tag=) with a calm heading and the parent family's description as subtitle. - Replace the flat "Explore by topic" strip with four calm family bands (Discovery & Wonder / People & Kindness / Solutions & Progress / Mind & Craft) from /api/families; zero-count tags hide until tagging fills them in. - Mood nav stays the primary emotional layer; the brief stays the front door. - /api/families fetch is non-fatal so the page degrades gracefully when the B1 backend isn't deployed yet.
