+# v1.2.3 uptime log noise reduction (2026-08-04):
+# - Uptime text sensor now uses coarse bucketed display instead of minute
+#   precision: "< 1 hour" / "> N hour(s)" / "> N day(s)" / "> N month(s)" /
+#   "> N year(s)" / "> N year(s) N month(s)"
+#   Buckets update once per hour (first day), once per day (first month),
+#   once per month (first year) — eliminates per-minute state churn in
+#   the HA activity log
+# - Added global last_published_uptime (std::string) to track the last
+#   published bucket value; the uptime lambda only calls publish_state
+#   when the bucket string actually changes
+# - Singular/plural handled in C++ (1 hour vs 2 hours, 1 day vs 2 days, etc.)
+# - Conventions: 1 month = 30 days, 1 year = 12 months — consistent with
+#   the existing d / 30 month convention used elsewhere in the file
+#
 # v1.2.2 stability fixes (2026-04-28):
 # - Added CONFIG_ESP_TASK_WDT_TIMEOUT_S = 40 to give the watchdog extra headroom
 #   during heavy JSON parsing when full price data arrives (~13:55+)
