/**
 * Equirect per-splat tile-coverage count.
 *
 * Reads:   screenX, screenY, radius, tsz, gox, goy,
 *          uniforms.groupTilesX, uniforms.groupTilesY
 * Defines: writes coverage[i]
 *
 * The X tile range can extend past the image edges into negative or
 * `> groupTilesX-1` indices — those represent the same splat seen
 * across the ±π longitude seam. Coverage is the raw X span (capped at
 * groupTilesX so a splat with radius > image_width doesn't emit
 * duplicate tile keys); emit-pairs walks [minTXraw .. maxTXraw] in
 * lock-step and applies a modular wrap when writing tile keys. Y is
 * clamped normally — equirect doesn't wrap across poles.
 *
 * @param maxCoveragePerSplat - Hard upper bound on per-splat tile count.
 * @returns WGSL source for the equirect tile-coverage block.
