Chrome cannot anchor a background-attachment: fixed layer inside a
backdrop-filter ancestor, so the composer's attach button baked the blurred
wallpaper against its own box and read as a solid, mismatched tile (often a
dark crop of grass) next to the pale field. Inside .glass-panel /
.study-chrome / .glass / .tabbar the nesting chrome (surface tokens,
white/xx fills, chips, cards) now drops the bake and keeps its flat token
fill - the panel's own blur is the glass - mirroring the existing
.glass-sheet carve-out. The composer's textarea keeps its brighter field
recipe (exempted via :not()), and .aero .btn-ghost gains the same carve-out
so the study pager's arrows sit flat in the pill.
Probe: the attach tile samples the band glass (115,137,118) instead of a
dark mis-crop (73,102,77). All 15 suites green, contrast scan clean.
