"""The dashboard: six tabs in the header, one viewport, no scrolling. Layout contract. The page is a fixed three-row grid pinned to the viewport height: header, tab bar, then a content region that takes the remaining space and never overflows the fold. Each tab lays its panels out on an internal grid sized in fractions of that region, so nothing depends on content height. Where a panel genuinely holds more than fits (the daily records table, the methods prose) that individual panel scrolls internally while the page frame stays put. Below 1024 px the constraint is released, because pinning five panels into a phone viewport produces unreadable eight-pixel type, and a phone user expects to scroll anyway. Visual language carries over unchanged from the previous station page: slate-950 ground, glass panels, Jakarta for prose and JetBrains Mono for anything numeric. The one new structural device is the tab bar, and it earns its place. Five distinct questions (what is it doing, what will it do, what did it do, is the model any good, how does it work) were previously one long scroll where the important things sat below the fold. The signature element is the estimator internals panel on the Live tab. Most weather dashboards show numbers. This one shows the state estimator working: self-heating coefficient, Kalman innovation, novelty distance and drift pressure, all ticking at 2 Hz. It is the part of the system that is normally invisible, and watching a filter converge is the most honest possible demonstration that there is real machinery underneath.

where it lives

Indoors the building governs temperature and humidity, not the sky. Pressure passes through walls, which is why precipitation runs on tendency.

enclosure

Closing a door changes how strongly the sensor couples to outside. The heads carry about 55 hours of memory, so tell them rather than waiting two days.

24 costs about 11% of one core. 16 is still fluid and a third cheaper. Below 12 the crossfades judder.

Site and model

altitude feeds the sea-level reduction on every row

Psychrometric humidity correction

Moves RH from the element's temperature onto air temperature. Off by default: measured against a reference this board read 75.4% where the truth was 50.4%, so it reads high and this would push it higher.
