/*
  llembas.eu — one stylesheet, no build step.

  The look is the LLeMbas server's own: a dark terminal palette ("Moria") with a
  phosphor-leaf brand colour and ithildin-cyan accents, a parchment light theme
  ("Shire"), square corners, hard offset shadows, and a monospace face for the
  chrome. Every colour resolves through a custom property on :root.

  Layout rule: anything that sits side by side lines up by construction —
  shared grid tracks and subgrid, never alignment by coincidence.
