   Scrimptech — "MU/TH/UR 6000" theme  (v3)
   --------------------------------------------------------------------------
   Green-phosphor ship-computer console: monochrome green on black, all-caps
   terminal labels, CRT scanlines + vignette + bloom. Amber/red survive only
   as caution/critical accents.
   Visual-only, layered on top of each page's own <style> block and loaded
   LAST, so these rules win. No page content is changed.
   To revert: remove the <link rel="stylesheet" href="aliens.css?v=3"> line.
