- Equipment cache: add freshness gate so only 1 Oracle query per 5-min cycle
across 4 gunicorn workers; sync worker waits before first refresh
- Portal: add frame-busting to prevent recursive iframe nesting
- Hold Overview: remove redundant TreeMap, add Product & Future Hold Comment
columns to LotTable
- Hold History: switch list.sql JOIN from DW_MES_LOT_V (WIP snapshot) to
DW_MES_CONTAINER (historical master) for reliable Product data; add
Future Hold Comment column; fix comment truncation with hover tooltip
- Page status: reorganize drawer groupings
