-// SKELETON — portable monitor EDID not captured yet. On first use at the

+// Two PM1601 16" panels in portrait beside the laptop panel.
+// Applied by symlinking this file to cfg/display.kdl (see scripts/desk.sh).
+// Panels are keyed by EDID identity, NOT by connector name — connector names
+// reshuffle between docks; identity travels with the panel. Long names copied
+// verbatim from `niri msg outputs` (2026-10-30).

+// The laptop sits 420 px down so its centre (960) meets the centre of the
+// 1920-tall panel band — no dead corner where the cursor crosses.
+// Modes are the panels' reported preferred modes, copied verbatim: niri
+// matches mode strings exactly and silently falls back to preferred on a
+// miss, so a typo here costs the refresh rate without an error.
+// Reasoning: omp-docs/tools/niri/displays.md ("The config pattern").
