-  ABSOLUTE VS. RELATIVE TIMESTAMPS:
-    "marker info" reports timestamps in absolute milliseconds (e.g. Time: 3349892.250ms).
-    These are NOT relative offsets -- they are raw profile-internal timestamps.
-
-    DO NOT use them directly as bare numbers: "pq zoom push 3349892,3354100" is WRONG
-    because bare numbers are treated as seconds from profile start.
-
-    Instead, use --absolute to pass them directly:
-      pq zoom push 3349892.250,3354100 --absolute
-
-    Or compute the relative offset by subtracting the profile start time shown in "pq status":
-      pq zoom push 892.250ms,4100ms   (if profile starts at ~3349000ms)
+    --absolute   Treat bare numbers and ms values as absolute profile-internal ms
+                 (use with the absolute values shown by "marker info")
