User report on Frigate post-fix: water still glitches between two patterns
and still changes with view angle, unlike the sky (which uses the same
skyPortBeginFan/skyPortEmitTileShift mechanism post-D227 and no longer has
this problem). The mechanistic writeup and GE_D227V trace from the same
session looked correct but were evidently not sufficient evidence -- a
single static frame/angle capture never exercised whatever actually causes
the live symptom. Reopening honestly rather than leaving a stale FIXED
label; the superseded analysis is kept in the row for reference but flagged
as unconfirmed. No code change in this commit (docs only).
