// How to Read It
Use vCurrent for the file people should always open and keep editing. Take a _yyyymmdd snapshot when you want a frozen copy of that current version as of a date.
Use vX (e.g. v1, v2, or a short label) with a date for a specific, finalized version you intend to keep and refer back to.
Dates are always yyyymmdd — e.g. 20260721 — so files sort chronologically by name.
