Format and check markdown with prettier in make fmt and fmt-check (closes #110)
check / check (push) Failing after 3s

script/fmt and script/fmt-check follow the model scripts in the prompts
repo: Go as before, plus prettier over every markdown file with 4-space
tabs and proseWrap always. Prettier is pinned by hash in package.json and
yarn.lock; script/bootstrap now installs node, yarn and prettier. The
Dockerfile lint stage copies node and yarn from a node image pinned by
hash and runs script/bootstrap, so its make fmt-check fails the build on
unformatted markdown. Every markdown file is formatted once; wording is
unchanged (CLAUDE.md's "*" list markers become "-").

# BIP85 - Deterministic Entropy From BIP32 Keychains
This package implements [BIP85](https://github.com/bitcoin/bips/blob/master/bip-0085.mediawiki), which allows for deterministic derivation of entropy from a BIP32 master key. This enables a single seed to generate multiple wallet keys, mnemonics, and random values in a fully deterministic way.
This package implements
[BIP85](https://github.com/bitcoin/bips/blob/master/bip-0085.mediawiki), which
allows for deterministic derivation of entropy from a BIP32 master key. This
enables a single seed to generate multiple wallet keys, mnemonics, and random
values in a fully deterministic way.
## Overview
BIP85 enables a variety of use cases:
- Generate multiple BIP39 mnemonic seeds from a single master key
- Derive Bitcoin HD wallet seeds (WIF format)
- Create extended private keys (XPRV)
