Thermograph monorepo: graded-climate API + SSR frontend + infra, domain-specific containerized deploys
Search Console shows impressions skewing hard to °C countries — India, South Africa, New Zealand, the UK, Australia — while every climate page rendered °F into the HTML. Search snippets quote the server-rendered text, so a reader in Delhi saw a temperature they had to convert in their head before the page was worth a click. Climate pages now render temperatures in the city's country convention: °F for the US and the handful of other Fahrenheit countries, °C everywhere else. This happens server-side, so it holds with no JS and shows up in the snippet. data-temp-f keeps the raw Fahrenheit in every case — it stays the conversion source of truth, and climate.js repaints from it on toggle exactly as before. The visitor's stored choice still wins over everything; the page default only sits between that and the locale guess, so a first-time visitor stops seeing a °F→°C repaint on load for the majority of our traffic. The unit rides on a ContextVar rather than a parameter because _temp() is reached from both directions — templates call it as a Jinja global, and the context builders call it directly to pre-render the records tables into strings. Threading an argument would mean touching ~20 call sites across three levels of nesting, where missing one yields a silently wrong unit instead of an error. The scope wraps the context builder as well as the render, since the builder is evaluated as an argument and runs first, and it resets in a finally: the page handlers are sync `def`, so Starlette runs them on a recycled threadpool thread and a value left set would leak into the next request that thread serves. Conversion rounds half-up to match JS's Math.round rather than Python's round-half-to-even, so the server prints the number climate.js would and there is no flicker on load for a visitor whose unit already matched. Pages with no single city — the homepage strip, the hub, the interactive views — set no scope, emit no data-unit-default, and keep today's locale behaviour. Precipitation, wind and humidity stay imperial; that inconsistency is worth a follow-up but is outside this change. Two existing assertions were passing for the wrong reason: base.html.j2 mentions "°F/°C" in an HTML comment, so a bare `"°F" in html` check succeeded even on a page whose every temperature was Celsius. They now read the rendered spans. Claude-Session: https://claude.ai/code/session_013dRZmX9D3JEntfMKWMTWZ8 |
