* Planet size formula moves to pixel-space: `pointRadiusBasePx = 2 + 2 * cbrt(size / SIZE_NORMALIZER)`. The on-screen disc now reads ~4-7 px at the reference zoom regardless of how large the world rectangle is — the previous `world-units` formulation blew up on small maps and made Source-class planets swallow their neighbours. * Labels + outlines live in the origin copy only. The 9× replication across torus copies was the dominant cost on a 100+ planet map (Pixi.Text creation + Graphics rebuilds on every zoom step); the origin-copy layout is what the camera-wrap listener guarantees the user actually sees. * `setPlanetLabels` and `setPlanetOutlines` skip Pixi-object rebuilds when the input fingerprint is unchanged — toggle flips and selection changes now keep the existing Text / Graphics instances alive and only repaint the affected pieces. * `renderer.md` updated to the new contract.
