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.

Adopt the PageEnter wrapper as every page's outermost render element and remove the ad-hoc per-page entrance motion.div wrappers. Every page now enters the same way — all top-level sections rise+fade in, staggered — so nothing appears instantly and the motion is identical app-wide. Presentation-only: no data/logic/hooks/invalidate/permissions touched. Embedded sub-tabs (CompanySettings, ReceivedInvoices), Login (auth shell) and the dev UiKit are intentionally excluded. Gates: tsc -b --noEmit=0, build=0, vitest 152/152.
