/* ── the hub shell, FLUID (2026-09-04 late) ─────────────────────────────────
   Lesson: theme-pure pins the contents rail at a fixed 352px and caps the work
   column at 660px; the first desk build offset the desk by fixed pixels and
   centred it on wide screens, so on Raghu's viewport the rail sat on top of the
   cards. Now: the rail width is a clamp of the viewport, the desk sits in the
   space to the RIGHT of the rail (centred within that space, never behind it),
   and the desk's own columns come from a container query on its real width —
   not from the viewport. No fixed pixel offsets remain. */
