The zero-content-area guard (layout-guards + paint.ts) suppressed ALL
children of a Box whose inner content rect collapsed to zero, including
position:"absolute" children. An absolutely-positioned child is placed
against the containing block (border-box), not the content rect, so Ink
v7.0.4 paints it (verified by running real Ink: a w=2 h=2 single-border
box with an absolute child renders "┌┐#\n└X"); vue-tui dropped it,
rendering "┌┐#\n└┘".
- layout-guards: exempt POSITION_TYPE_ABSOLUTE children from the hide loop
so they keep their layout.
- paint: move overflow-clip setup above the zero-content early-return and,
in that branch, paint only absolute children (still clipped by
overflow:hidden, matching Ink) while keeping in-flow children suppressed
(the blessed degenerate-box divergence).
Flow-child suppression and overflow:hidden clipping both stay Ink-aligned
(verified byte-identical against real Ink). Known limitation: an absolute
descendant nested under a suppressed in-flow child is still dropped (the
flow ancestor is removed from layout) — scoped to direct absolute children.
