Three fixes against the v0.39.0 user feedback. - Layout exception "BoxConstraints forces an infinite height". `_PillarRow`'s wide-window path used `Row(crossAxisAlignment: CrossAxisAlignment.stretch)` inside a `Column` inside a `SingleChildScrollView` — Row inherits unbounded height, can't stretch to anything, Flutter throws. Wrapped the Row in `IntrinsicHeight` so the Row's height is bounded to the tallest child first. Same shape `_DocsRow`'s narrow-window path was triggering with `Wrap` + `SizedBox(width: double.infinity)` — replaced with a plain `Column` for that path; the wide path keeps the Wrap with the proper finite cardWidth. - Dropped the "WIE ES ZUSAMMENPASST" / "HOW IT FITS TOGETHER" section header. Operator-feedback was that the label sounded like a question without an answer. The hero already establishes the page; the three Hub/Module/Flow cards are self-explaining beneath it. Header was visual clutter and the underlying ARB keys are gone. - Reordered the sidebar: Welcome, **Store**, Doctor, Flows, Audit, Approvals. Store is the operator's daily-use surface and belongs above Doctor (which is a diagnostics page). Welcome stays slot 0 as the first-launch landing.
