The Globe pattern cartographer-trade note is corroborated by the official 25w07a
cartographer-trade description below; it is not an asserted Bedrock trading recipe.

The loom adds ordered layers with one dye per step; the ordinary loom limit is six pattern layers.
Special pattern items are reusable. A background-colored masking step still counts as a layer and uses a dye.

Original work:
SVG geometry, flat swatch choices, descriptive explanations and A–Z letter combinations
in lib/banner.ts were independently authored for MakePixelArt. No recipes, source code,
artwork or game textures were copied from MakeBead. There is no third-party data license
grant implied by the Minecraft client reference above; official names and identifiers
are used as factual reference information.

Previews are schematic approximations, not exact in-game textures. The Thing entry
uses a text placeholder instead of reproducing a logo. Special charges use original
simplified icons. A few letters are deliberately angular or shortened: see letterNotes.
The recipes use only ordinary loom patterns and at most six layers. They were checked
against the pinned data/tag registry, not played through in a running game. Changes in
resource packs, lighting, texture proportions, future releases or other editions can
change appearance or requirements. No universal latest-version claim is made.
