/* ============================================================================
   almanark — "quiet observatory" design language

   Night-blue chrome · warm almanac paper for content · one muted brass accent ·
   hairline rules, no rounded cards, no decorative shadows. Times and 干支 sit in
   a tabular monospace so columns line up like a printed ephemeris.

   Deliberately NOT the two neighbours: speccalcs is warm-white + print blue +
   Source Serif (a printed data handbook); pixiroll is cream + brown + teal +
   rounded Nunito (an island). This one is nocturnal and instrument-like.

   Deliberately NOT a 算命站: no red/gold, no gradients, no glow, no emoji.
   The only saturated surface on the page is the header.

   CJK deliberately uses the system stack. A traditional-Chinese serif webfont is
   several MB even chunked; PingFang TC / Microsoft JhengHei / Songti render this
   content well at zero cost. Only the Latin monospace is self-hosted, because the
   thing that must look exact is the numerals.
