Erik 0d3b85dd69 docs(issues): file #48 — subset of tree species hover above terrain
A few specific scenery GfxObjs render with their trunk base ~0.5-1.5m
above the terrain mesh while the vast majority sit flush. Per-GfxObj-
id ⇒ deterministic across instances. Player Z snap is unaffected.
Side-by-side with retail confirmed the same species place flush there.

Filed with three competing hypotheses: per-GfxObj origin convention
(some tree meshes authored with origin at bbox-center vs trunk-base),
physics-vs-bilinear terrain Z mismatch on NE↔SW-cut cells, or the
same DIDDegrade close-detail story as #47 applied to scenery.

Detailed cut-and-paste handoff for the next agent at
docs/research/2026-05-06-issue-48-handoff.md — covers the diagnostic
dump that disambiguates the hypotheses with one log line per
offending tree.
