/* Khoj by Swadesh Nai Swarga.
   Two themes keyed on :root[data-theme]. js/theme-early.js sets it before first paint from a saved
   choice, else from prefers-color-scheme, so the page never flashes the wrong theme. The no-JS
   fallback is the media query below. Red as TEXT always uses --accent-text: SNS red (#C1121F) is
   only 2:1 on the dark ground, so it is kept for fills. */
