Add Settings > Учебный каталог, off by default and available on ordinary writable profiles. Load ready example boxes, photos, TTKs and linked sample inventory additively; preserve own data, saved orders and edited examples when hiding or re-enabling. Respect company/profile scope, read-only permissions, failed downloads and tenant changes. Preserve the opened recipe guide across real catalog refreshes on iPhone. Integrated feature checks and full pull-request QA passed. Standard main QA and exact-asset production UI verification remain in place.
Add compact accessible client summaries and menu discounts in percent or rubles with explicit durations. Preserve ordinary catalog prices and order line snapshots; derive current prices and expire promotions automatically without background writes. Keep fractional prices, legacy sale compatibility, and regression coverage. Full pull-request QA passed. Publication remains gated by full main QA and byte-for-byte production asset and UI verification.
setupOldButton() polled the DOM every 4s forever after the menu editor
first opened, with no way to ever stop - the interval id was not even
kept in a variable. It now returns whether the button was found, the
interval only starts when the first attempt fails, and clears itself
on the first successful attempt (also wired into the existing
disconnect() cleanup alongside the other timers).
