/**
 * F-Gas Calculator by EgoLog — styles.
 *
 * One centred card: gas field on top, then three aligned tiles (mass in,
 * tCO2e out, GWP out), then the working. Every selector is prefixed
 * `egofgas-` and every custom property `--egofgas-`, so the file can sit next
 * to the existing EgoLog stylesheets without touching anything they own.
 *
 * Where the host page already defines the `--legal-*` tokens, they win; the
 * fallbacks keep the widget correct when it is used stand-alone.
