Page weight

We sum the uncompressed HTML and every referenced local stylesheet, font, script, icon and image, including lazy-loaded images. Shared assets count once per page. It is a conservative cold-load payload, not a browser measurement; HTTP headers and compression are excluded.

CO₂

At build time, @tgwf/co2 applies Sustainable Web Design model v4 to that byte count, using its defaults and no verified-green-hosting claim. Results are model estimates with substantial uncertainty, not measured emissions or a promise about any particular visit.

Czech grid now

The grid indicator comes from a local JSON file. Its sample value is clearly marked as a placeholder and is not used in the per-view estimate. The supplied hourly workflow can update it from a configured source and trigger a rebuild. Without a configured source it leaves the placeholder unchanged.
