Fix scrolling on desktop and mobile

- Fix desktop: use fixed height on .main-content so overflow-y: auto
  creates a proper scroll container (min-height prevented scrolling)
- Fix mobile: override to height: auto and overflow: visible so the
  body handles scrolling naturally
- Fix touch swipe handler blocking vertical scroll by restricting
  swipe detection to left edge zone and raising preventDefault threshold
- Move @import out of :root block (invalid CSS, font may not load)
- Add overflow-wrap/word-break to prevent long URLs causing horizontal scroll
- Add overflow handling for markdown content (pre, code, table, img)
- Add overflow: hidden on top-nav and max-width guard on mobile nav-content
