Wiring notes

• Gen 5 / series: 'riviera' / CTA → /quiz matches ski/jetset persona pattern.
• Insert card treats riviera as persona (isPersona, badge, analytics persona_riviera).
• Docs pool table updated for Riviera paths.

Nits (non-blocking)

• Series badge/kicker labels are nested ternaries in three places (ReelInsertCard, Reels, Watch). Fine for now; a tiny seriesBadge() helper would age better if another wave lands.
• /watch hero copy drops carpet/café mention while chips remain — intentional prioritization, not a bug.
