The form screens' pinned title and legend lost their gradient blur when
GamepadTrayScrim went (2590238b): the scrim was `.ultraThinMaterial`, and a
material by definition lifts and tints whatever it blurs — it read grey over
the aurora, and washed with the palette's ground it read coloured. There is
no public way to blur a backdrop without that tint, so the layer was deleted
rather than re-tuned, and the rows have scrolled to a raw edge since.
Glur's GlurView blurs the backdrop through a gradient with NO material stage
on top — the rows soften as they slide under the pinned trays and nothing
carries a colour. Three things about the adoption are deliberate:
- It is the library's GlurBackdrop product, which uses a private API
(a variable-blur CAFilter on UIKit/AppKit). The public `.glur()`
modifier is a Metal shader on a view's OWN content and silently no-ops
over platform-backed views like ScrollView, so it cannot reach a
backdrop at all. GlurBackdrop ships as a separate module precisely so
adopters can weigh the App Store exposure; it disables hit testing
itself, so the band never eats a touch.
- The dependency is pinned by REVISION: GlurBackdrop exists only on main —
no release carries it (the newest tag, `1.1`, predates it and is not
three-component semver anyway, so `from:` resolution stops at 1.0.4,
which doesn't have the product). Wired into BOTH manifests — the
package for `swift build`, and the xcodeproj (remote package reference
+ per-target product deps) for the app targets, which compile these
sources themselves and know nothing of Package.swift's dependencies.
- The band takes NO content-side overhang, unlike the scrim it replaces —
and dropping the scrim's hard-won -44/-72 runway is the point, not an
oversight. That runway existed because a material carries body at every
alpha and had to dissolve OUTSIDE the tray; carried over here it blurred
fully-visible rows at rest (first on-glass verdict). Glur's ramp reaches
literal zero, so the band ends exactly at the tray's layout edge: open
content untouched, rows soften only where they actually slide under.
The 80 pt outer bleed and the pinned shape
(`transaction { $0.animation = nil }`) are kept — full-bleed by LAYOUT
rather than `.ignoresSafeArea()`, so a push never shows the band
growing into place.
Mounted exactly where the scrim was: settings, add-host and pair trays
(top + bottom) and the library title (top). Glur is attributed on the
Acknowledgements screen alongside the bundled font — it is a Swift package,
so the Rust-closure notices generator rightly knows nothing about it.
macOS build, tvOS typecheck; band placement and the blur itself verified on
the iPad on glass.
