- D402: first clean Linux build fix (shim include-cycle + _SHIFTL).
- D403 (new): Deck front-end logo/copyright page broken + graphics not
updated is a test artifact — the bundle was seeded with 0.3.0-era
sidecars that predate the D75/M-197 blob fix and D303; not a code
regression. Disambiguation: regenerate the Deck's data/ sidecars.
- D404 (new): 'Aim style: Centred (PC)' is inert on a gamepad; the row's
doc comment over-promises (applies to pad trigger) but the centred
path is mouse-only (input.c:1783, D337 device-aware gate).
- Deck test confirmations: D175 gains a low-utilisation (~15-30%)
frame-pacing/present data point; D395 pad-binding retest satisfied
(not stuck); D401 rumble + D287 idle/resume-from-sleep confirmed on
the Deck's Steam Controller / SteamOS.
