+**Acquisition**:
+The single read of a Series page made the moment the Series first exists, giving it
+both its Latest Chapter and its Cover without waiting out the Poll queue. Distinct
+from a Poll in the two ways that matter: a Reader is present — it is triggered by
+their first Bookmark of that Series — and it is the only read that establishes a
+Cover rather than refreshing facts. It happens once in a Series's life; every later
+read of the same page is a Poll.
+_Avoid_: initial poll, first fetch, prefetch, warm-up

 **New Chapter**:
 The state where Latest Chapter is ahead of Progress. The single condition the ember
 accent is permitted to signal.
