/* Long-form reading typography for /insight/<slug>/ article pages.
 *
 * A NEW file rather than an edit to _astro/advisory.BztH4tH_.css: that filename is
 * content-addressed, so editing it in place while keeping the hash would leave
 * cached clients on stale bytes.
 *
 * Uses only the existing design tokens, plus one addition:
 *
 *   --link-prose  #4fa89f  6.94:1 on --bg
 *
 * The brand accent --primary-bright #2a6b65 computes to 3.17:1 against --bg #0a0c0c,
 * which FAILS WCAG AA (4.5:1) for text. Using it for in-body links — the obvious
 * move — would be an accessibility failure on every article. It stays for decorative
 * use (list markers, blockquote rule) where the text-contrast rule does not apply.
 * --ink-dim is 7.30:1 and passes AAA, so the site's established voice carries into
 * long-form body copy unchanged.
