Anchored overlay placement: Flip decisions ignore the overlay height · case 03

Flip decisions ignore the overlay height.

Member previewVariant 3 · 3 implementations · 10 checks per implementation

Case contract

Place below with a gap when fully fitting; otherwise above; align left edges and clamp both axes so oversized overlays start at zero.

Why this case matters

A deterministic model of anchored overlay placement; this isolates one interface invariant without requiring a browser.

One recorded failure

This sample comes from the broken implementation of a controlled reproducer.
