/*
 * TEJAS DIXIT PORTFOLIO — style.css
 * Mobile-first rewrite of the Flask portfolio.
 *
 * KEY FIXES vs original:
 * 1.  font-size: 1rem (16px) on all inputs/textareas  → kills iOS Safari auto-zoom
 * 2.  terminal-card: white-space wraps              → no horizontal scroll on 320px screens
 * 3.  letter-spacing on h1/h2 relaxed for small vp  → legible at 320px
 * 4.  nav-menu: max-height + overflow-y scroll       → long menus don't overflow viewport
 * 5.  .section padding scaled via clamp()           → no wasted space on short mobile
 * 6.  touch targets ≥ 44×44px on all interactive    → WCAG 2.5.5
 * 7.  safe-area-inset padding for notched phones    → content behind iPhone home bar
 * 8.  project-grid single col → 2 col → 3 col       → readable at every width
 * 9.  hero min-height uses 100dvh (dynamic)         → no jump when mobile browser chrome hides
 * 10. metrics grid: auto-fit keeps 1–3 col          → never overflows
 * 11. social-grid 2→3→4 col at sensible breakpoints → legible labels
 * 12. .btn min-width removed; btn-block for forms    → no tiny tap targets
 * 13. prefers-reduced-motion respected              → accessibility
 * 14. color-scheme: dark declared                   → system UI matches
