/*
 * astrodexa.com — the page's own layout, on dexa-style.
 *
 * Every colour, size, face and radius here is a dexa-style token, and every
 * button, card, chip, label, section and page head is a dx- unit from
 * base.css (copied from the pinned tag by build.sh). This file holds only what
 * the kit does not: the header bar, the masthead, the feature and plan grids,
 * the footer, and the legal-page column. No hex values, no local button or card
 * recipe: adopting a unit means the local copy is gone (STYLE-CONTRACT R5).
 *
 * Light is the default; dark is :root[data-theme='dark'], which the tokens
 * answer by themselves. Nothing here needs a theme rule.
