 >It seems the clocks going forward and depriving people of sleep did cause extra heart attacks, but only in people who would have had a heart attack at some point anyway. The heart attack merely happened sooner. And likewise, the clocks going back gave people a rest and bought them a few more days until their heart turned on them. This could be relevant information for a hospital planning its staffing around when the clocks go forward, but it does not mean daylight saving time is net dangerous.

+[Window Management](https://manual.raycast.com/window-management) is built-in; snapshot-based **Window Layouts** (save current positions → re-apply later) require [Raycast Pro](https://www.raycast.com/pro).
+
+Raycast can place windows on specific monitors and resize to halves/quarters, but **cannot** react to events (app launch, screen unlock). For "run on unlock", use Hammerspoon below.
+
+**Setup: apply a saved layout at screen unlock**
+
+1. Position windows manually (Raycast → `Move Window to Next Display`, `Top Half`, etc.)
+2. Raycast → `Create Window Layout`, name it
+3. Raycast → `Window Layouts` → select layout → Actions → `Copy Deeplink`
+   - Deeplink looks like: `raycast://extensions/raycast/window-management/apply-layout?id=XXXXXXXX`
+4. Pass the deeplink to Hammerspoon's `screensDidUnlock` (see below), or run it via `open -g <deeplink>` in a shell script
+
+> First-run note: Raycast may prompt "Always Open Command" the first time a deeplink fires.
