+> World → `Vec<Quad>` ordenado por pintor para [dominium](../README.md).
+
+Toma un snapshot del `World` ([`dominium-core`](../dominium-core/README.md)) y produce una lista de `Quad { x, y, w, h, color, depth }` ordenada por pintor (back-to-front). Sin tocar el mundo — sólo lee. La proyección 30° viene de [`dominium-iso`](../dominium-iso/README.md). Output consumible por cualquier renderer (Llimphi/vello, WebGL, SVG).

+
+Takes a `World` snapshot ([`dominium-core`](../dominium-core/README.md)) and produces a list of `Quad { x, y, w, h, color, depth }` ordered painter-style (back-to-front). Doesn't touch the world — only reads. 30° projection comes from [`dominium-iso`](../dominium-iso/README.md). Output consumable by any renderer (Llimphi/vello, WebGL, SVG).
