A cape texture is 2,048 pixels and only 372 of them are ever drawn

The file is 64×32, the cape lives in a 22×17 corner, and the side people actually see is 160 pixels — under 8% of the image. Plus the one-pixel offset that catches everyone.

A trimmed armour set has 1.57 billion possible appearances, which is why the lock button exists

199 states per slot to the fourth power. Rerolling all four at once will never converge on a look — locking the pieces you like turns an unsearchable space into a workable one.

A Minecraft username is 1–16 characters of exactly three things, and a UUID has two spellings

Letters, digits, underscore. No hyphens, no dots, no spaces. And a UUID is accepted with or without its dashes — which is why one lookup fails and the identical one works.

A Bedrock skin pack is four files, and two of its failure modes are silent

Two UUIDs that must differ, a lang file that is not optional, and skin keys that strip punctuation — so 'My Skin!' and 'My Skin?' become one skin with no error.

Bedrock has no standalone cape pack — a cape only ships attached to a skin

There is no cape-only .mcpack format. Every cape must be paired with a skin entry that names it, which is why a cape pack is really a skin pack with an extra PNG per entry.

Slim or classic is decided by 24 pixels, and you can see exactly which ones

A skin is slim if fewer than 6 of the 24 pixels at (46,20)–(47,31) are opaque. Plus the full UV map, why legacy 64×32 skins get mirrored, and why Bedrock's 128×128 will never load in Java.
