merge.wgsl warps one camera-space tile into one output chunk — output pixel to direction (the projection maths of dr_pano::projection, verbatim), direction to the frame's camera, camera to source pixel, bilinear by hand from four textureLoads because rgba32float is not filterable — and adds it into a storage-buffer accumulator weighted by its distance from the frame's edge. A resolve pass divides by the weights and packs sixteen-bit samples at the sensor's scale with a coverage bit. MergePass::merge drives it: bands of rows, chunks across a band, and for each chunk only the frames whose footprint meets it, each rendered as the source rectangle the chunk needs and nothing more. The working set is one chunk, one tile and one band (FR-MRG-11); the frame textures are the caller's to cache. Feathered, not seamed; gain a scalar per frame — the blend quality is panorama.md §10's step 5, after the path writes a file.
