The buttons all read fully bright once PadRIO went live. Two causes:
1. The lamp value is a BITFIELD (RP412 LampLevel): bits 0-1 flash mode,
bits 2-3 state1 brightness, bits 4-5 state2 (flash alternate). My
code treated any non-zero as bright. Now decode it: solid -> state1
level; flashing -> alternate state1/state2 at the flash rate. Level
0=off, 1-2=dim, 3=bright.
2. Diagnosed (BT_LAMP_LOG): the pod lights EVERY mapped button's lamp to
a uniform DIM baseline (0x14 = state1Dim+state2Dim, L4Lamp
NotifyOfStateChange) -- 'button present, function idle' -- and only an
ACTIVE function to bright (0x3C). So the dim baseline is on all
buttons; rendering it at RP412's dim red (150,44,28) made the whole
field look lit. Darkened off/dim so the idle field reads as unlit
dark keys; bright (active) keeps RP412's full values and pops.
Verified: idle cockpit shows dark/subdued button keys, not an all-lit
field; the lamp decode animates flash modes and lights bright only on an
active function.
