/* ============================================================================
 * scott_common/public_shell.css  [v0.79.0]
 *
 * Shared PUBLIC marketing chrome — responsive header + footer + family cross-nav.
 * Ported from sr-trucking's marketing/base.html (the best public site) and
 * generalized so every Scott marketing site (recycling / plastics / trucking /
 * superstore) shares ONE responsive frame while keeping its OWN menu + content.
 *
 * Per-site theming flows through two CSS custom properties set inline on the
 * page root from SCOTT_COMMON_BRAND (see context_processors/shell_brand.py):
 *     --public-brand     : the site's primary brand color (header bg, accents)
 *     --public-accent    : the CTA / highlight color (gold-equivalent)
 * Sensible Scott-navy defaults below so the shell renders even unthemed.
 *
 * This file is FRAME-ONLY. It deliberately does NOT style hero/sections/forms
 * (those stay per-site so content density differs). Sites keep their own
 * body/section CSS.
