// NEON GRID CITY — the retro synthwave flyover: wireframe-neon towers on
|
|
// glowing grid streets under a striped sun. Style "retro" swaps the window
|
|
// fills for neon cell edges and paints the sky cylinder with the banded
|
|
// sun disc; the street grid runs hot pink and pumps on the pulse. Pattern
|
|
// taught: one engine, three looks — `style` reskins the same static mesh
|
|
// entirely in the pixel shader, so a doc flip is a full genre change.
