Cargo features

OS backends follow target_os (no empty Cargo feature toggles). Optional features:

linux (default) — gtk + x11rb for _NET_WM_WINDOW_TYPE_DESKTOP pin
image-prefetch (default) — host-side remote image.url → data: URI with disk/memory TTL cache (ureq). Not linked on Android (target-gated; Kotlin localPath owns remote images). Disable on desktop/iOS/macOS/Windows to drop TLS from the dependency tree.
rasterize — SVG→PNG data-URI for Adaptive Cards chart/canvas/gauge/shape/zstack, gradient backgrounds, and image.systemName glyphs (pulls resvg). Without it, Windows Widgets Board falls back to emoji TextBlock for SF symbols. Enable for Windows Widgets Board parity.
workerw — Windows wallpaper WorkerW parenting
layer-shell — Wayland gtk-layer-shell Background (requires linux)
macos-private-api — transparent macOS desktop widget webviews (also enable Tauri macosPrivateApi in conf)
schema / codegen — JSON Schema / TS codegen tooling (dev)
