/* Guardian Sphere — house style.
 *
 * THE RULE THAT KEEPS THIS OFF BROWN: on ivory, gold is a RULE and a MARK,
 * never a word. Gold dark enough to be legible on ivory IS brown, so the moment
 * gold becomes a text colour the whole app's accent turns brown. Links are ink
 * with a gold underline; kickers are neutral caps beside a short gold rule.
 *
 * Corollaries, each of which was a separate mistake somewhere else:
 *   · the grey ramp stays NEUTRAL. Mix it toward the gold and most words on
 *     screen go brown, because secondary copy and captions all ride that ramp.
 *   · structural borders are ink-tinted. One gold hairline is jewellery; two
 *     hundred is a brown grid under everything. --rule-gold is spent deliberately.
 *   · no webfont request. This is a site about protecting a household's network;
 *     it does not phone a third party to draw its own headings.
