- Eurostar scraper now fetches both Standard and Plus (PLUS class code)
prices/seats in a single API call; each service dict gains plus_price
and plus_seats fields
- GWR fares scraper gains fetch_advance() which makes two sets of
paginated calls (standard advance + first-class advance) and returns
cheapest per departure; shared _run_pages() generator reduces
duplication in fetch()
- New /api/advance_fares/<station_crs>/<travel_date> endpoint returns
advance fares as JSON, cached for 24 hours
- Results page gains NR ticket selector (Walk-on / Std Advance / 1st
Advance) and Eurostar selector (Standard / Plus); total column is
JS-computed from the selected combination with cheapest/priciest
highlighting
- Load advance prices button fetches the API lazily; if advance fares
are already cached they are embedded in the page and applied on load
so the button is hidden automatically
