v1.1.2 - Mocha Steam

Backdrop blocks squashed. The acrylic accent now carries a dark Catppuccin mantle tint (~0.88 alpha) instead of no tint, so a bright app behind the window (Discord) can no longer read through the theme as bright patches with hard edges. The sidebar panel is 0.9 (was 0.8) and the Mica Transparency option moves to 75, so the remaining bleed is tiny. Measured after: sidebar flat within 1-2 levels over its full height, library content within ~6 (blur gradient), against 20-30 before. Details in docs/mocha-steam.md section 11 and docs/dwmx-acrylic-plugin.md.
