// @solidrt/2d - an instanced sprite layer above @solidrt/core/gpu.
// A layer's atlases bound together, N quads in one draw per VIEW: a layer
// holds the sprites and shows only through its views (layer.createView /
// <View2d>, each a target with a camera of its own - a Unity scene renders
// only through Cameras, a Godot World2D only through Viewports); every
// frame names its texture, so sprites from several sheets interleave in
// the one draw (the PixiJS/Phaser multi-texture batch). The live layer
// (createSpriteLayer/addSprite) backs every sprite with a SPATIAL ARENA
// node whose Pose2D record sink writes the pose instance buffer at the
// core flush, so core producers reach sprites and picking walks the core
// BVH; style stays a JS-written second instance buffer. The records layer (createRecordLayer)
// is the raw escape hatch for motion only JS can compute: 20 JS-owned
// floats per sprite in a mirror, published by dirty range through the
// 3d record mesh's verbs (records/updateRecords/setRecordCount). The baked
// tile layer (createTileLayer/TileLayer) is the static sibling: a tile
// world baked into chunk textures the core's residency gate brings and
// takes as the camera moves, drawn through its views as a few quads,
// re-baked on change. What any layer's pixels look like is its MATERIAL
// (material.ts): the stock `unlit()` with its blend and its
// prelude/surface slot, or a shaderMaterialClass over the layer's GLSL
// set (`@solidrt/2d/glsl`), with per-sprite style records in any vertex
// format - the same three tiers and the same words as @solidrt/3d, the
// material sitting on the layer because the layer is the batch. Two
// faces throughout: the imperative core (usable without Solid
// components) and the components (SpriteLayer/Sprite/Group/
// View2d/TileLayer) on top. Sheets reach the GPU through createAtlas,
// sliced by grid/namedFrames/fullFrame, and a mipmapped sheet is extruded
// first (extrudeGrid/extrudeRects). See AGENTS.md for the model and the
// traps.
