/* hadianlabs.com — one stylesheet for every page (PUBLIC_SITE §8).
 *
 * Hadian Labs is the neutral parent: paper, ink and hairlines, the same neutrals as curevise.com.
 * Colour belongs to the products — Curevise's teal appears only inside its own panel. Light only:
 * this site carries no script, so it has no theme switch.
 *
 * Same-origin only: the font and the images are served by this site and nothing else is fetched.
 * No @import, no escape sequence, and no off-origin reference in any position — check_site_egress
 * refuses them, and every page's policy refuses the request. */
