 * paridity.com. Light page body per the EGMW light-mode standard, with the Paridity palette of the
 * brand kit (docs/governance/brand/brand_kit.md in the product repository; press kit "Brand assets"):
 * a restrained zinc base with one orange accent. Orange points; neutrals do the work. The header,
 * the hero bands and the footer are the dark chrome (Primary Dark) that the white-on-transparent
 * Paridity logo requires, with the one orange rule beneath the header, as on the collateral.
 * Same stylesheet shape as EGMW-Org/IntelliWarp-Site.
