/* ImposterShield shared styles.
 *
 * Every page used to carry its own copy of the tokens. That is exactly how the site ended
 * up split down the middle on 2026-08-18: the homepage was moved to the warm light theme
 * and the other five pages stayed near-black, so "Free scan" dropped you from a cream page
 * onto a black one. Tokens live here now.
 *
 * The palette rationale, from the homepage redesign: near-black plus amber is hazard-sign
 * colouring and reads as a threat dashboard. The audience is non-technical and often older,
 * so the page should feel like help rather than a security console.
 *
 * NOTE: index.html still has its own inline copy of these rules. It is a bigger page with a
 * lot of one-off layout and was left alone rather than risked; if you touch the palette,
 * change it in both places until the homepage is moved over too.
