Make the grain texture universally visible via a fixed overlay

Browse source 
Previously the grain lived on .page-texture's own background-image, so
any section with its own opaque background color (bg-neutral-50 bands)
painted right over it. Moved the grain to a fixed, full-viewport overlay
that sits on top of everything instead.

Also fixed a failed attempt at using mix-blend-mode: overlay for a
single theme-agnostic texture - that blend mode has almost no visible
effect on backgrounds this close to pure white/black, since its math
compresses toward the backdrop at the extremes. Back to plain alpha
transparency with separate light/dark speckle colors, moderate opacity.
