/**
 * Atotsugi Support Center — Site Design System
 * atotsugi-site.css v1.2.25
 *
 * Consolidated from the current XServer stylesheet; density hierarchy audit + Owners case hierarchy + full-site component audit integrated 2026-08-24.
 * v1.2.24 (2026-08-26): Removed text-wrap: balance from blog post H1/H2/H3 only; retained it for .atg-page headings.
 * v1.2.25 (2026-08-26): Added text-wrap: pretty to blog post H2/H3 only; blog H1 remains normal wrap and .atg-page headings retain balance.
 *
 * Quality baseline:
 * - H1: 36–56px / SP 32–40px
 * - H2: 30–38px / SP 26–32px
 * - H3: 20–24px / SP 19–22px
 * - Lead: 18–20px / SP 17–18px
 * - Body: 17px / SP 16px
 * - Note: 14–15px / SP 14px
 * - Body line-height: 1.8 / SP 1.75–1.8
 * - spacing scale: 8 / 16 / 24 / 32 / 48 / 64 / 80 / 96
 *
 * Principles:
 * - semantic HTML first
 * - WCAG 2.2 AA target
 * - responsive without essential JavaScript dependency
 * - ATG namespace to reduce Lightning / VK Blocks collisions
 * - no version-by-version override stacking
 * - Lightning owns fixed-header behavior; site CSS owns header appearance
 * - cards only where the information structure benefits from cards
 * - spacing expresses hierarchy: major themes > subtopics > short information units
