The HL feed's root cause, captured off the wire: Tidal 1.9 addresses its
superdirtShape packets /dirt/play, not /play — a decoder that accepted only
the documented address dropped every real packet while every synthetic test
passed. Also: the first-trigger log could die on a non-trigger datagram
(UnboundLocalError) and take the whole feed thread silently; the feed now
survives anything. The wordmark bakes generously, scans its own ink and
crops — font metrics ignored the letter spacing and cut the tail to
PARVAGU; pixels do not lie. Single instance by flock (exit 78, no restart
storm); the tray launches midiviz via systemctl --user start, per PLN; the
2x column experiment is retired to a uniform grid — 'a C1 move overlapping
C2 is bad taste'.
