+// Catalog of every pixel format the C++ side handles. The X-macro is a
+// flat list of names:
+//
+//   X(name)
+//
+// `name` is the canonical format identifier — both an internal FormatId
+// enum entry and the public string accepted by pixpat_buffer::format.
+// Each name resolves to a struct in `pixpat::formats::` (defined under
+// pixpat-native/src/formats/) that carries:
+//
+//   - the layout (subsampling, planes, components)
+//   - nested `Source` / `Sink` aliases for the matching I/O templates
+//
+// Adding a format = a row here AND a struct in the right
+// pixpat-native/src/formats/*.h. The codegen
+// (pixpat-native/codegen/gen_pixpat.py) parses this X-macro to learn
+// the format set; pixpat.cpp re-expands it to build s_format_info via
+// `formats::name::Source` / `formats::name::Sink`.
+//
+// FormatId is internal — the public C ABI deals in format names only.
