Detailed Description

Import-time transcode knobs, work arena, and destination atlas store.

Mirrors the producer configuration (jof_produce.h) minus the source (the import path streams the caller's encoded page bytes). Size work with jof_work_bytes() over the same caps and tile geometry. webp_work is the optional whole-frame arena for WebP pages (jof_webp_work_bytes()); leave it NULL to fail-closed reject WebP pages exactly as a JPEG/PNG-only reader always did. atlas is the append-only memstore backing the produced JOF atlas lives in and is paged from; it must out-live every tile fetch.

Invariant: tile_w / tile_h non-zero; work covers work_cap; atlas covers atlas_cap.; webp_work is NULL, or it covers webp_work_cap bytes.
