New `local.hyprland.workspaceRules` option binds workspaces to monitor connectors so each has a home screen; a consumer sets it from its own host config (empty by default). Soft binding — an absent monitor's workspaces fall back to an active one, so a laptop-only session still works. `$mod+o` / `$mod SHIFT+o` focus and move the current workspace to the other monitor. When rules are set, an `exec-once` nudges a single-monitor session to workspace 1 rather than a support monitor's high default. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# Per-monitor "home" for workspaces. Each rule pins a workspace to a monitor
|
|
# connector, so it opens there and Hyprland moves it back when that monitor
|
|
# reappears after an unplug. The connector names are host hardware, so the rule
|
|
# list is an option a consumer sets from its own host config (see the example in
|
|
# `hosts/example/home.nix`), not baked in here; empty by default, so the example
|
|
# host binds nothing.
|
|
#
|
|
# Soft binding: when a bound monitor is absent the workspace just falls back to
|
|
# an active one — every workspace stays reachable, so a laptop-only (no external)
|
|
# session works unchanged. The `default` keyword marks the workspace a monitor
|
|
# shows on connect.
