The API emits naive ICT timestamps ("2026-09-12T02:00:00"). The page fed
them to new Date(), which applies the BROWSER's zone: a viewer in Europe
parsed a 02:00 ICT reading as 02:00 CEST, five hours in the future, so
"Last updated" clamped to "0 min ago" forever; a viewer in the Americas
saw thousands of minutes. parseTs() now pins +07:00 on naive strings and
every display formats with timeZone: Asia/Bangkok, so the site shows
river time regardless of where it is opened. Daily/hourly chart buckets
key on the Bangkok calendar day instead of UTC getters.
The tile also gets a real stale state: past 3 h (RID is hourly) it turns
red, reads "Feed stale · last reading <day>, N h ago", and the header
pill switches from LIVE DATA to STALE FEED. Age shows hours past 2 h.
scripts/dev_proxy.py serves the working-copy dashboard with API calls
proxied to water.buildfor.life so browser-side changes can be checked
against live data (and any browser timezone) before deploying.
