Reworked the mainline and Daikoku Futo PA against real references (Wikimedia
aerials of Daikoku JCT + OSM way data for the junction) rather than guesswork.
- Divided carriageways: raised median kerb with dark anti-glare fence down the
centre, matching OSM (lanes=2, oneway=yes per carriageway).
- Edge containment: white concrete parapet topped by a dark metal railing --
the signature Shutoko silhouette -- backed by a kill wall so cars cannot
leave the deck.
- Palette corrected from dark grey to Shutoko pale concrete; asphalt lightened
to mid-grey to read correctly in daylight.
- Daikoku Futo PA: replaced the single straight stub ramp with a full loop road
encircling the parking apron (real loop ramps measured at 48m and 121m
radius), elevated on pillars, reachable from BOTH carriageways via on/off
ramps. Median and barriers open at those junctions so the ramps connect.
- Removed the old four-sided perimeter box; the apron now extends under the
ring, so there is no exposed edge to fall off.
Verified by executing MapBuilder headlessly under a stubbed Roblox API:
build ok, 823 road segs, 797 median segs (26 junction gaps), 1594 barriers +
1594 railings + 1594 kill walls, 72 ring segs at constant 389.6 radius,
apron covering the ring, all decks continuous at Y=46.
