Two products share one repo: HQ (internal client book, proforma billing,
call tracking) and Store (the GST retail product shipped to ~300 clients).
Different DBs, different audiences, different cadences — 60 of 75 commits
touch HQ, 2 touch Store.
Design: two repos. HQ inherits the existing history; Store starts fresh so
its history carries zero HQ bytes. Shared packages fork into each side,
trimmed to verified usage — safe because GST rates are dated DB rows, not
code, so the forked arithmetic has no reason to diverge.
Project tracking and conversion reporting are deferred: they don't exist
yet, and mixing new features into a mechanical move hides failures.
