- structure pins step 26px to 32px to 38px as you zoom in; at the close tier
an info ribbon extends from the pin (name plus one status line: blueprint
purpose, minute-bucketed build ETA, or first needed material)
- ribbons claim screen-space rectangles greedily by cluster priority so they
never overlap other pins or ribbons; losers fall back to hover tooltips
- hovered structure jumps above all markers via a leaflet icon z-index rule
- authoring clicks and draft-vertex drags snap to existing geometry
(vertices plus road/zone edges, closing segments included) with a live
snap preview; draggable handles, right-click delete, midpoint insert
- distant roads render one straight midpoint label, close roads curve text
along the path
- structure popover footer shows a live ETA countdown, status line shows a
friendly estimated completion timestamp
- attribution control credited to the unit and game, restyled to match
Add the Leaflet map page and client (markers, labels, layer toggles, shipment interpolation), the placement and authoring server actions, the map-features and map-import API routes, and the map styles including leaflet pane isolation so portals stack correctly.
