Customer Portal & Loyalty (PL-T198)

Logged-in customers land at /account/bookings, which renders three lazy-loaded buckets — upcoming, history, cancelled — each paginated 50 per page, so the page paints instantly even for power users with hundreds of past visits. Repeat-book lifts the configuration of any past booking (resource type, party size, food package) via POST /me/bookings/{id}/repeat, prefills sessionStorage, and redirects to /book/{lane} so the customer just picks a date — every other field is filled. The LoyaltyTierBadge component shows ChainPassport tier (regular / gold / platinum) with an animated progress arc towards the next tier; tier rules and thresholds come from the venue profile.

After a completed visit, the platform schedules an NPS prompt — when the customer next opens the portal, NpsPromptModal auto-opens (0-10 score plus optional comment), feeding both analytics and the marketing automation post-detractor recovery loop. Self-service rebook and cancel use CancelBookingDialog with a live quote preview (shows what fee/refund applies under the venue's cancellation rules), a reason picker, and party-size modify in-place. /account/gift-cards shows balance, expiry, and redemption count for every card the customer has added. /account/preferences exposes per-channel opt-outs (email, SMS, push) with an audit trail so support can see when a preference changed. The whole portal is tenant-branded via ChainWhiteLabelConfig, just like the booking wizard.
