Roadmap: post-v1 feature arc

[TorbenWetter]

Agreed feature arc after v1 (2026-07-05). Status: items 1–14 shipped; item 15 (trip posters) deferred to a future session. Process: one feature at a time → local testing → commit only after it's confirmed working. Trip posters intentionally last.

Infrastructure first

• 1. CI + one Playwright smoke test (typecheck, build, hermetic fixture-data smoke)
• 2. Country-agnostic core: extract Sweden specifics (extract URL, EPSG, admin levels, curated labels/seats) into a country config — repo stays Sweden, architecture doesn't

Cartographic craft

• 3. Road casings + per-class road colors/widths
• 4. Curved labels — sea names on arcs, river names via textPath
• 5. Vintage waterlines (concentric coastal rings, pipeline buffers)
• 6. Vector terrain: contour lines (gdal_contour) + Baltic bathymetry (GEBCO/EMODnet)

Data layers

• 7. Ferry routes (OSM route=ferry)
• 8. Kungsleden & major hiking trails
• 9. Lighthouses, airports, castles (icon layers)
• 10. E-road shields (E4/E6/E22 number badges)
• 11. Län name labels (area-aware placement)

Experimentation tools

• 12. Layer duplication (layer instances instead of fixed ids)
• 13. Color harmony lock (derive palette roles from one anchor color)
• 14. Palette-from-image (drop a photo → extract palette → map onto layer roles)

Finale

• 15. Trip posters — separate mode (not main studio UI): stage-based route data (from/to/date/transport), location-clustered photo picks, playful emoji markers
