Bulk Pricing: never raises a product above its current/sale price; picks the cheapest qualifying tier.
Sequential Order Numbers: numbers are assigned when an order is placed (not on draft creation), preventing gaps on block checkout; “set next number” can only move forward to avoid duplicates.
Order Rules: now enforced on the block-based (Store API) checkout as well as the classic checkout.
Email Designer: live brand preview; clearer warnings for non-order emails; corrected footer placeholder hints.
Coding-standards pass: prefixed all meta keys, moved inline scripts to enqueued assets, added output-time escaping, added readme and uninstall routines.
Translations now load on init to satisfy WordPress 6.7+.
