-- Change the default Omarchy look'n'feel.
--
-- Load order is Omarchy defaults -> current theme's hyprland.lua -> this file
-- (see $OMARCHY_PATH/default/hypr/omarchy.lua), so whatever is set here is the
-- last writer and wins over the theme. That is the point of this file: a theme
-- picks colours, the compositor's feel stays ours.

-- Omarchy 4's decoration defaults, pinned explicitly.
--
-- Stock quattro is flat and cheap: rounding 0, blur off, shadow off
-- ($OMARCHY_PATH/default/hypr/looknfeel.lua). Most third-party themes ship a
-- hyprland.lua that turns glass on instead -- Cyberdream and Spectra both did --
-- and on this box that is a bad trade: blur at size 6 / 3 passes over an eDP
-- panel plus a 5K Studio Display is real frame time on an iGPU sharing system
-- memory, and rounded corners plus per-window opacity make the Chromium and
-- Electron surfaces (which cannot paint a transparent background themselves)
-- show wallpaper where page background should be.
--
-- Turning blur off globally also neutralises any layer_rule blur a theme adds
-- for the Quickshell surfaces: a layer rule cannot blur while
-- decoration:blur:enabled is false.

-- Omarchy tags every mapped window `default-opacity` and fades it with this
-- rule; themes re-issue it with deeper values (Cyberdream used 0.98 / 0.92).
-- Window rules are last-match-wins, so restating the default here puts every
-- window that did not explicitly opt out of the tag back on stock fade.
-- Terminals keep their own alpha (kitty's `background_opacity`) on top of it.

-- Themes are also free to re-enable the workspace slide (Spectra sets
-- `workspaces` with its "flow" bezier); Omarchy's default is off. Restate it.
-- workspacesIn/workspacesOut are not overridden anywhere, so they inherit this.
