+// Summer_Time_Configuration.html has THREE DST modes (Disable, Recurring,
+// NonRecurring), each with its own full set of fields, ALL present in the
+// DOM simultaneously (JS shows/hides based on the selected mode) -- same
+// shape of problem as PortConfiguration.html's duplicate Link Speed fields,
+// except here several labels collide WITHIN one table (Month/Hours/Minutes/
+// Offset each appear once in the NonRecurring block and once in the
+// Recurring block). Rather than lean on generic xepage.go parsing and its
+// document-order last-wins behavior, this reads/writes via hardcoded field
+// names extracted directly with regex -- unambiguous regardless of DOM
+// order.
+//
+// Only Disable and Recurring are supported; NonRecurring is rejected
+// outright rather than guessed at (it uses a different, absolute-date field
+// set: Month/Date/Year/Hours/Minutes, v_3_1_1..v_3_10_1).
+//
+// Confirmed live before this was wired into a resource: submitting mode +
+// only the Recurring block's fields (omitting the NonRecurring block
+// entirely) was accepted with no err_flag and no FILTER_MISSING -- unlike
+// PortConfiguration.html, this page does NOT require hidden hold_all_fields.
