BB AI redesign: 4-item nav, Show coverage, About, status bar, wire ticker,

trends sidebar, Ask BB AI, neural-summary schema, 13-event seed.

Phases 1-10 (11 phases minus Phase 8 which is the pgvector marker).

DB:
  bb.events                — 13 industry events seeded (MPTS, ANGA COM,
                             BroadcastAsia, SET Expo, IBC, NAB NY,
                             NewTECHForum, SATIS, DPP EBS, SVVS,
                             Hamburg Open, CABSAT, NAB Show '27).
  bb.article_events        — composite PK (article_id, article_table, event_id)
                             links any article-table row to one or more events.
  bb.banner_creatives      — (no change tonight)
  bb.{native_articles,
      ai_rewritten_articles,
      wp_imported_posts,
      press_releases}.neural_summary jsonb — populated by Phase 7
                             analyzer (deferred).
  bb.{native_articles,
      ai_rewritten_articles}.featured boolean — featured carousel source.

Routes:
  /api/events/upcoming     — date-gated, enriched with is_live/days_until/
                             day_of_event/total_days.
  /api/ask-bb-ai           — Claude Opus 4.7 chat with prompt caching on
                             the system block, 30-msg/hr/IP rate limit.
                             Tool-use deferred — first cut is straight
                             LLM with archive-citation prompting.

Pages:
  /show-coverage           — index of all events, upcoming + past split.
  /show-coverage/[slug]    — hero + status (live/T-Nd/past) + schema.org
                             Event JSON-LD + tagged articles list.
  /about, /about/{team,contact,advertise,press-kit}.

Components:
  Header                   — 4-item nav: Show coverage (dropdown) /
                             Newsletter / Forum / About (dropdown).
                             Old NEWS/GEAR/TECHNOLOGY/ADVERTISE items
                             removed from nav (routes still exist).
  EventsDropdown           — 340px CSI panel with L-corner brackets,
                             pulsing dot, "BB AI" badge, live/T-Nd rows,
                             auto-updated stamp.
  AboutDropdown            — 5-item lighter treatment.
  SystemStatusBar          — Index online pulse, articles/sources/events
                             counts, build version. Above Header.
  LiveWireTicker           — replaces NewsTicker. [HH:MM] [SRC] prefix,
                             CSS marquee, doubled for seamless loop.
  TrendsSidebar            — BB AI detected trends, top 5 entities by
                             7d-vs-30d lift, vector-pass stamp.
                             Phase 6b: replace with pgvector.
  AskBBAI                  — floating bottom-right button + 420px right
                             drawer chat. No mention of Anthropic/Claude.

Styling:
  redesign-tokens.css      — --color-text-info, --color-background-*,
                             --font-serif/mono/body, bb-pulse/bb-ring
                             animations + bb-marquee.

Constraints honored:
  - LiveU 728x90 still between </nav> and ticker.
  - Blackmagic 300x600 still pinned top of sidebar.
  - /r/[slug] click tracking unchanged.
