/**
* iPad-width regression guard (portrait, 768×1024).
*
* Two invariants this viewport class kept losing:
*
* 1. No horizontal page overflow — the content column must shrink
* below its children's intrinsic min width (`min-w-0` on the
* shell column); wide children scroll inside their own
* `overflow-x-auto` containers instead of widening the page.
* 2. The content column keeps its room: with no stored sidebar
* preference, tablet widths start on the icon rail (w-16), so
* `<main>` gets ~704 px of the 768 — not the 512 px left over
* next to the expanded 256 px sidebar.
*
* Desktop project only — the assertions are viewport-driven via
* `setViewportSize`, and the Pixel-5 project covers the phone class.
