The product catalog demo left most inspectors with little to show. Angular Travel behaves like a real booking site: destinations with filters kept in the URL and an @ngrx/signals store, trip pages loaded by a resolver, a Signal Forms booking flow with an unsaved-changes guard, a guarded My Trips page with a reactive sign-in form, and the DevTools Lab restyled to match. Istanbul comes first.

Review comments at @src/app/app.html:
- Line 32: Update the sign-out flow in the app component so clicking the Sign
Out button clears the account and then navigates to the sign-in route; route the
template click through a component method that performs both actions instead of
calling account.signOut() directly.
Review comments at @src/app/examples/http-example.ts:
- Line 55: Move the aria-busy binding using products.isLoading() from the
Products section to a wrapper around the results content, keeping the
role="status" text outside that busy region so loading updates remain
announceable.
Review comments at @src/app/pages/booking.ts:
- Line 32: Update isoDay to format the adjusted Date using its local year,
month, and day rather than converting it to UTC with toISOString. Keep the
YYYY-MM-DD output so earliest remains consistent for the date input minimum and
validator.
- Around line 649-650: Add a Number.isInteger validation rule to the
traveler-count validation alongside the existing min and max checks in the
booking schema, so fractional traveler counts are rejected before submission.
Review comments at @src/app/pages/home.ts:
- Line 49: Replace the `$any($event.target)` cast in the input handler with a
typed template reference to the input element, then read the reference’s `value`
when calling `query.set`.
Review comments at @src/app/pages/trips.ts:
- Around line 270-274: Update the trips computed property to filter
upcomingTrips() by the signed-in account’s email before mapping bookings. In
cancel, verify the booking exists and belongs to the signed-in account before
calling store.cancel or showing the success message.
Review comments at @src/app/travel/travel.store.ts:
- Around line 86-87: Update the store’s booking commit logic around the
destination lookup to reject bookings when travelers exceed the destination’s
remaining seats, leaving both booking and destination state unchanged. Handle
that rejection in the booking page’s submission flow so it does not report an
unsuccessful booking as completed.
- Line 82: Update the booking ID generation for the created booking so it uses a
source that remains unique after cancellations instead of deriving IDs from
store.bookings().length. Preserve the TRV- prefix and ensure previously issued
IDs are never reused.

Navigate away after signing out.
When /trips is open, account.signOut() clears the account but does not navigate. The route guard runs only during navigation, so Trips remains mounted and continues to show bookings and cancellation controls.

Review feedback. Booking ids came from the number of bookings, so they repeated after a cancellation; they now come from a counter in the store. The store rejects bookings with more travelers than seats left, and the booking page says so. My Trips only shows and cancels the signed-in account's trips, and signing out leaves the page. Also require a whole number of travelers, compute the earliest departure in local time, keep the loading status outside the busy region in the HTTP example, and read the home search input through a template reference instead of $any.

Review comments at @src/app/examples/http-example.ts:
- Line 290: Update the skeleton styling around the pulse animation to disable it
when the user prefers reduced motion, using a prefers-reduced-motion: reduce
media rule while preserving the existing animation for other users.
Review comments at @src/app/pages/booking.ts:
- Around line 674-682: Add the submitted requests value to the booking record
created by the `this.store.book` call in the booking submission flow, so dietary
and accessibility instructions are preserved.
- Line 672: Update the booking submission flow around the 600 ms delay so
confirming departure cancels the pending action before it reaches store.book, or
prevent departure until submission finishes. Preserve the existing booking
behavior when the traveler stays on the page.
Review comments at @src/app/pages/destination-detail.ts:
- Line 64: Update the group-size fact in the destination detail view to use the
selected destination’s group-size value, ensuring Northern Iceland shows a
maximum of 10 travelers; if per-destination values are unavailable, remove the
fixed number from this fact.

Review feedback. A booking submitted just before leaving the page was still created after the traveler chose to discard it; the submit action now stops when the page is gone. The special requests field is saved with the booking. Also stop the loading skeleton pulse when reduced motion is on, and show each destination's own group size instead of a fixed "Up to 12".

What and why
The product catalog demo left most inspectors with little to show. This rebuilds the demo app (
src/) as Angular Travel, a small booking site where every inspector has real data:@ngrx/signalsstore (withState,withComputed,withMethods)/examples) restyled to match, with all existing examples keptpublic/destinations/CREDITS.md)Split out of #36 to keep that pull request reviewable; the two don't depend on each other.
