# Outputs by monitor identity (`umbriel outputs` → "Config name"), so the
# settings follow a display across ports. Unlisted displays use their preferred
# mode at scale 1.
#
# Scale: the externals land near 110 logical px per inch (the ultrawide's
# native density), so a window keeps its size moving between them. The laptop
# panel runs denser (112) at 2: 1280x800 logical.

# Layout: the laptop panel sits at the origin and each external display sits
# directly to its left (negative x), bottoms aligned. The externals are used
# one at a time, so they share that slot. Positions are logical, so a
# display's offset is its scaled size.
