# DigiDala — Alpha50.4 Changeset

## Goal

Close the two manual-QA defects found in Alpha50.3 without changing the agreed Pix economy or paid-Mandala copy.

## Scope

- Expose the server-side `cell_price_pix` in the paid Mandala detail API payload.
- Add an API regression assertion for the Support Mandala price.
- Stabilize the Pix purchase-row layout on narrow screens: preserve visible spacing between `Количество pix` and the package selector and keep the `Купить` button at a fixed compact width.
- Update Mini App cache-busters and version to `0.4.0-alpha.50.4`.
- Preserve Alpha.50.3 microcopy and existing Pix purchase behavior.

## Acceptance criteria

1. Support API detail returns `cell_price_pix: 95`.
2. The Support persistent microcopy shows `Стоимость клетки 95 pix. Пополните баланс за Telegram Stars для участия в этой мандале`.
3. Sandbox and free Creative microcopy remain unchanged.
4. The Pix purchase row shows visible spacing between `Количество pix` and the package dropdown.
5. The `Купить` button remains fully visible and does not get squeezed on narrow Telegram screens.
6. Full automated project checks remain green.
