redesign the site as a technical minimalist TUI

Replace the glassy hero treatment with a terminal and TUI vocabulary
while keeping the layout minimal:

- Switch the type stack to JetBrains Mono and flatten every surface:
  hairline borders, square corners, no blur or glow, and a faint
  graph-paper grid in place of the radial gradients.
- Rebuild the home hero as a terminal window whose output is typed in
  on load; the old mouse-parallax glow script becomes that typing
  sequence, and it no-ops under prefers-reduced-motion.
- Give the projects, about, and entry panels title bars, and render
  cards with a metadata strip, status dot, ISO date, and prompt-style
  links.
- Hide the inline nav behind the hamburger on narrow screens; the old
  rule was outranked by the #menu id selector and never applied.
- Add an SVG favicon, which also clears the only 404 on the site.
