/**
 * Insights knowledge centre — editorial styling.
 * Built on top of the Zoom Psychology brand tokens defined in style.css
 * (--clr-blue, --clr-sky-blue, --clr-light-blue, --clr-bright-blue, --clr-grey).
 *
 * Sizing follows the theme's 62.5% root font-size (1rem = 10px) and mirrors
 * the site's own breakpoint cadence (1150 / 900 / 650 / 500 / 450) so the
 * section feels consistent with the rest of the site rather than oversized.
