Thermograph monorepo: graded-climate API + SSR frontend + infra, domain-specific containerized deploys

Emi Griffith 01e5f48257 Add a °F/°C unit toggle to the header (#23) ... A shared units module in nav.js holds the active unit (persisted), converts Fahrenheit API values for display, and notifies pages to repaint on a switch. A segmented °F/°C control is injected into the top-right of every header (left of the view tabs); Weekly, Day and Calendar convert every temperature — cards, dense timeline, trend chart axis/labels, tooltips and the PNG export — while wind, humidity and precip stay as-is. Compare keeps its Fahrenheit comfort slider, so the toggle is hidden there.		2026-07-11 08:10:40 +00:00
