/*
 * Success-Led Selling — marketing static site.
 *
 * The four inviolable color rules (from .kilo/agent/color-enforcement.md):
 *   Rule 1: #000000 background, #CFFF04 text — pages, body, containers, cards.
 *   Rule 2: #000000 background, #FFFFFF text — secondary labels and metadata.
 *   Rule 3: #CFFF04 background, #000000 text — buttons, highlights, active tabs.
 *   Rule 4: #FFFFFF background, #000000 text — printable output only (print
 *           media below). Every white background carries an explicit color:#000.
 * Exception colors (text only on black): #ff9800 callout headings.
 *
 * Mobile-first. Breakpoints: 768px (tablet), 1024px (desktop).
 * Touch targets: buttons and interactive controls are minimum 44px high.
