/*
 * DII homepage composition presentation (P2-WP-07 DII Homepage Composition;
 * Approved-Design Conformance), loaded on the front page only. It lays out the
 * governed sections (Hero, Value Strip, Featured + Latest editorial zone,
 * Explore Topics) and the structural Assurance Strip; the Radar keeps its own
 * stylesheet (dii-radar.css).
 *
 * Tokens: DII tokens, plus the shared Foundation scale with fallbacks. Tints
 * and on-dark colours are derived from the approved navy and teal with
 * color-mix(); no new brand colour, no external font, no image and no
 * JavaScript. Layout is fluid: a controlled content width, grids that reflow,
 * and no fixed heights, so long titles and summaries never clip. Breakpoints:
 * 48rem (tablet) and 64rem (desktop). Bands (Hero, Assurance) reach the
 * viewport edges with a pseudo-element while their content stays in the
 * content width.
