Detail-page headers put their action buttons in a flex row with flexWrap:"wrap", so on a phone the 2-4 buttons (Potvrzení / Zahájit realizaci / Smazat, etc.) wrapped into a ragged grid. New shared `headerActionsSx` (ui/PageHeader): on xs it's a full-width column (each button its own full-width row); from sm up it's the usual right-aligned wrapping row — desktop unchanged. A StatusChip kept in the same group stays its natural size (alignSelf) instead of stretching. Applied to PageHeader's own actions slot and every detail-page header action group: Order/Offer/Invoice (both views)/Project + the Warehouse Receipt/Issue/Item/Inventory detail headers. Verified in Chrome at 430px on OrderDetail: the group is flexDirection column with all three buttons at the same x, full-width, stacked. tsc -b --noEmit, npm run build, vitest 152/152 clean.
