v0.3.0
Makes the per-order purchase limit visible in the storefront. Previously the limit was enforced server-side but the UI often failed silently: quantity steppers just stopped at the cap, and AJAX cart updates (theme auto-update, mini-cart drawer) swallowed the rejection notice.
- A "Maximum N per order." note now appears under the Add to Cart button and under each affected cart line.
- Typed-in quantities above the cap are clamped client-side before theme AJAX handlers see them, with the note flashing red (or a temporary inline warning where no note is present).
- The note and warning only appear when the per-order limit — not stock — is the binding constraint.
