"""
Control Board Monitor — v1.0
Changes requested:
- POST behavior matches the sample app by default: POST "/" with form body "Variable" + "value".
Switch via POST_MODE = "sample" | "legacy" (default="sample").
- Robust variable selection: case-insensitive canonical keys, no duplicates, stable Treeview IDs.
- Threshold logic exactly as specified, with color gradients:
DEAD_LOW (<dead_low) → yellow/orange; LOW [dead_low, low) → yellow (stronger near dead_low);
OPERATING [low, high) → green; HIGH [high, extreme_high) → red (stronger near extreme_high);
EXTREME_HIGH (>= extreme_high) → deep red. Default alarms ON for DEAD_LOW & EXTREME_HIGH.
Spec alignment:
- Discover POST actions from WEBSERVER_LIST_VARIABLES_JSON ("POST:").
- Discover variables & poll with WEBSERVER_BATCH_GET (bulk).
