/**
 * template-dash.css — section-based dashboard layout primitives.
 *
 * Loaded by every category dashboard page (406, 569, 570, 578, 588, 589,
 * 590, 613, 614, 615, 409), the front page, template-about.php, and
 * template-reports.php. Self-contained: these pages load only this
 * stylesheet (plus the global style.css) for shared dashboard primitives.
 *
 * Historical note: this file started as a pilot for category-578, then
 * absorbed the primitives that used to live in dashboard.css as each page
 * was migrated off the legacy stylesheet.
