Propose alternative routes: another autoroute + a toll-free départementale way

Add favourites, price-freshness + 24/7 filters, services in popups, sortable list

Quality pass: CI, accessibility, and gzip/perf

Reliability + accuracy + features: routing fallback, tolls, EV price, filters, trends, dark mode, URL state, social card

Deeper SEO, Apache-2.0 metadata, full ADEME car scrape, chargers when zoomed out

Fix narrow-screen layout overlap + make author credit always visible

Add price-ceiling slider, first-visit install prompt, SEO metadata + author footer

Add real-time geolocation (locate button + live position) and motorway (autoroute) prices in itinerary cost

Fix mobile UI: slim top bar + controls pushed below it, both panels collapsible to chips (collapsed by default, mutually exclusive on mobile)

Add 'Électrique' option to the fuel panel to display EV chargers (replaces itinerary checkbox)

Add real car models (ADEME) + hybrids, EV selector + national charger layer + recharge stops; split JS/CSS into files; verbose container logs
