/* =====================================================================
 * Aware — Risk Briefings (blog)
 * Dark-brand listing + long-form article styles. Linked AFTER
 * colors_and_type.css and site-chrome.css on every blog page. Nav,
 * footer, buttons, language toggle, mobile sheet, and the locale-aware
 * type foundation all come from the shared files — NOT redefined here.
 *
 * Layout decision: the article uses a single centered reading column
 * (.post-wrap, 760px) with an in-flow heading anchor offset for the
 * sticky nav. No TOC sidebar — briefings are short, scannable, and read
 * cleaner as one column on every breakpoint.
