  Neon-terminal theme for the resource pages (/content/<id>/ only; the
  homepage and admin keep the explorer look). Loaded after each page's own
  <style> and after site-chrome.css, so it layers on top of both.

  Pieces: phosphor palette (CSS variables shared by every page variant),
  CRT scanlines + vignette, glowing mono headings with a blinking cursor,
  inverse-video links, terminal-window code blocks, ASCII rules.
