Two defects with one cause: a tint name that means a frozen hex. "primary" is the legacy alias of literal #ffffff, not Theme.text-primary, so every control passing it drew a white glyph. On the eleven light themes that is white-on-light -- the header back/forward chevrons, the sidebar toggle and the carousel arrows the owner marked. They now pass the theme-following names, which icon_tint_qt bakes at runtime. The stale `hslLightness > 0.5 ? "primary" : "black"` workarounds that predate the runtime tinter collapse into those names, and the qrc floor underneath them becomes polarity-aware: dir_for() returns "" whenever the cache dir is unavailable, a bake fails or the theme document has not been published, and that path used to resolve textPrimary straight back to the white bake -- reproducing the bug it was fixing, app-wide, in the degraded state. On accent fills the fix is a deviation from Slint, approved by the owner after measurement. A fixed white glyph on Theme.accent falls under 2.6:1 on 16 of the 35 shipped palettes, including high-contrast at 1.70:1 and wcag-dark at 1.82:1 -- the two themes whose reason to exist is contrast. Slint hardcodes #ffffff there (CircleAction.slint:72 and three others), so the bug is upstream. accentText alone is not the answer either: it is picked for the theme's text ramp and gives 2.56:1 on Rose Pine Dawn, worse than the black it replaces. So QbzTheme picks the best-contrast tint by real sRGB luminance against the live accent, and the labels beside those glyphs use its colour twin -- BrowseGenreButton and LibraryView were drawing a white glyph next to an accentText label inside the same pill. Rounds out the two parity items the same files owe: QbzNavButton gains the ambient arm from Carousel.slint (wired at the six carousel sites, not left dead), and QbzCircleAction rounds its glyph to whole pixels the way CircleAction.slint does. cc
