Product naming
The official product names are chematic and chematic-draw. Both stay
lowercase, including at the beginning of a sentence. Do not add an extra
leading s, and do not capitalize the names as ordinary title-case words.
CI checks current public text and package metadata with:
Historical benchmark records, archived documents, internal identifiers, and frozen wire-format values are outside this branding check. They remain stable so naming cleanup cannot rewrite evidence or break compatibility contracts.
