Distribution & updates
────────────────────────────────────────────────────────────────────

Although the source is GPL, the OFFICIAL distribution channel is the
Invum License API:

  - Faz 1: purchase → email with zip + license key
  - Faz 1.5: WordPress Plugin Updater hook against the License API
  - Faz 2: a Lite version on WordPress.org with a Pro upgrade path

Pro features are bundled in the same package; they are gated at runtime
via `\Invum\Pos\License\Client\License::is_pro_active()`.  Holding
the source does not, by itself, activate Pro features — that requires a
valid license + activation against the License API.
