Summary

After the v7 migration, public APIs are Uint8Array-first, but some docs/JSDoc text still says "Buffer" in places where the canonical wording should now be "Uint8Array" (with optional note that Node Buffer is a Uint8Array subclass and remains accepted for compatibility).

Why

This can mislead users into thinking Buffer is still the primary API surface.

Scope (docs-only)

• README wording cleanup where appropriate
• JSDoc wording cleanup in source comments
• Keep compatibility note where Buffer input remains accepted

Non-goals

• No runtime behavior changes
• No API signature changes

Acceptance

• Docs consistently describe Uint8Array as canonical public type
• Compatibility statement remains explicit for existing Buffer-accepting paths
