+# --- Warm up OFF-camera so the first visible frame already has FULL charts ---
+# Live gauges are not enough: the sparklines are right-aligned over the whole
+# chart width, so a short warm-up shows a thin trace clinging to the right edge
+# and reads as a dashboard that just booted. The window here is ~328 samples
+# (the status line prints it as `span 5m28s`: ~120 chart columns x 2 samples per
+# braille char at the 1s default interval), so the warm-up has to cover it — 7s
+# filled 2% of the chart, 40s only 12%. Sleep the whole span and the first
+# visible frame is already a dense trace. Cost is wall-clock on an off-camera
+# sleep; the GPU workload is already running by then, so the history it fills
+# with is real load, not idle.
+# (vhs `Sleep` takes ONE unit — `5m30s` is a parse error; use seconds.)
