A solo freeskate mode (`?opponent=freeskate`; the desk Mac app boots into it): one rider on the long park, no opponent, guns, clock or rounds. - Half-pipe at the park's start (two 540-radius quarter circles); vert airs lock straight up and land back in; pumping builds height; a dash breaks out over the coping. Boards stay on concave faces, a crossed coping is a lip launch, one gravity both ways in vert, lower rolling drag. - Loops are solid track in the ground's material, clickable, ridable from ~2,500, pumpable, and pay out 10% on completion. Heads can ride them. - Momentum after Runman: runs carry speed, dashes stack into overdrive that bleeds back, hits cost a share; the skate stick only pushes, a board dash is a kick-push, stepping off keeps the roll. - Boomerboard: hold B (enter) and the deck boomerangs home, even to a head. Double-down releases the board so it can be caught again. - A lone head rolls on the board's physics, half-pipe and all, and clicks a register lower. Steep faces are walls on foot and in the air, so nothing clips up through the pipe. - Freeskate wraps endlessly to the right across the park's 9,000-unit period; the drawn ground is rebuilt when the world resizes (it stopped at the station's width); no station decks or roof over the park; the freeskate jump is back to the station's height; a speed readout. - Plain sky replaces the underpass photo; photo materials keep the normal palette. Shadows follow the floor with round caps. Legend labels wear their button's colour; START is plain white. - Mac app: the realistic theme via a textured Metal path, the glyph atlas wipes only between frames (title flicker), trackpad pinch/rotate/scroll orbit the camera (the skatepark camera honours yaw and pitch and keeps a loose board in frame), the window title animates, and the icon sits on a proper Mac plate. Labs: `node --test --test-name-pattern "half-pipe|loop lab"` prints pass-by-pass air heights and loop entry/exit speeds. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
