/* ===========================================================================
 * borgnames.com — Shared site chrome & page-shell styles (Story 2.1)
 * ---------------------------------------------------------------------------
 * THE single non-brand stylesheet. It styles the header, nav, footer, page
 * layout, and the structural placeholder shells used by all five pages
 * (home / pillar / supplies / about / privacy).
 *
 * It CONSUMES the brand tokens from brand/tokens.css and never redefines a
 * brand color / type / spacing / radius value — every paint references a
 * var(--bn-*) token. No forked palette literals live here. (The only literal
 * colors are transparent-overlay rgba() values keyed off brand hues, noted
 * inline.) No duplicate jug lives here either — the one jug is brand/jug.svg.
 *
 * ZERO BUILD. Plain CSS. Load order on every page (exactly these requests,
 * no per-page extra stylesheet):
 *
 *     <link rel="stylesheet" href="brand/tokens.css">
 *     <link rel="stylesheet" href="brand/brand.css">
 *     <link rel="stylesheet" href="site.css">
 *
 * Relative hrefs are used everywhere (not root-relative "/...") so the plain
 * checkout works from file:// as well as any static host — every page file
 * sits at the repo root next to brand/.
 *
 * Mobile-first: base rules target a 390px phone; a single min-width media
 * query widens line lengths and the nav for desktop.
