// Client-side temperature converter for the server-rendered climate/city/record
// pages. Those pages render every temperature as `<span class="temp"
// data-temp-f="72.3">72°F</span>` (see content.py `_temp`/`_temp_bare`) so the
// value is real in the HTML for crawlers and no-JS visitors. Here we rewrite each
// span to the active unit on load and whenever the °F/°C toggle changes — reusing
// the same unit machinery as the interactive pages. Importing units.js also boots
// its toggle-injection IIFE, so this one script gives the pages a working toggle.
