Anchored overlay placement: Overlay width is omitted from right-edge collision handling · case 04

Overlay width is omitted from right-edge collision handling.

Member previewVariant 4 · 3 implementations · 11 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

Sample boundary fixture

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