/* ═══════════════════════════════════════════════════════════════════
   PMO Portal — Responsive Stylesheet
   Scope  : Login + Dashboard only (Phase 1 & 2)
   Desktop: 1024px+  → untouched (no overrides at ≥1024px)
   Tablet : 768–1023px
   Mobile : ≤767px
   Small  : ≤374px (iPhone SE, Galaxy Fold outer)
   
   Strategy:
   • All rules are additive — desktop CSS is never removed.
   • Uses CSS custom properties already declared in login.html / main.css.
   • Zero inline styles. Zero !important unless unavoidable.
   • Flexbox / Grid layout only — no float / position hacks.
