 Builds paired diffuse + height PNG atlases for the Sporel map-lib v0.3.0+ format.
 
+**v0.2.0** adds edge-replicated padding (Rev 4 §13.3), `--schema blob-14` slot
+validation (E1), a `collision.json` sidecar (E2 validation + pass-through), and
+alpha-analysis that sets a per-tile `tile.opaque` flag. Source tiles may be
+PNG, WebP, or JPG (decoded via jimp).

+### Flags
+
+| Flag | Meaning |
+| --- | --- |
+| `--in <source-dir>` | Directory of source tile images. |
+| `--out <atlas-dir>` | Output directory for the baked atlas + sidecars. |
+| `--atlas-id <stable-id>` | Stable atlas identifier written into the lock. |
+| `--tile-size <N\|auto>` | Tile edge length in pixels, or `auto` to infer it from the source tiles. |
+| `--max-size <N>` | Maximum atlas dimension in pixels (default 4096). |
+| `--pad-px <N>` | Edge-replicated padding (gutter) applied around each tile, in pixels (Rev 4 §13.3). |
+| `--schema <blob-14>` | Slot-validation schema for the source set. `blob-14` is the v0.2 14-slot blob schema (E1); required by lib-core.maps v0.5.1. |
+| `--lock <existing-lock.json>` | Reuse an existing lock to keep tile indices stable. |
+| `--blocks-sight-pattern <regex>` | Regex matching tile names that block line of sight. |
+| `--verbose` | Print detailed per-tile diagnostics. |
+
