/* ==========================================================================
   StatusPulse marketing surface — "Instrument"

   Thesis: this is a measurement instrument, not a brochure. The page is built
   from the vocabulary of one — a graticule grid, hairline rules, calibration
   ticks, tabular numerals — rather than the gradient-and-glass vocabulary of a
   generic SaaS landing page.

   The rule that governs everything: COLOUR IS RESERVED FOR SIGNAL. The page is
   monochrome ink on near-black. The only saturated colour anywhere is
   green / amber / red, and only where it means operational / degraded / outage.
   An operations product that spends colour on decoration is advertising the
   opposite of the discipline it sells.

   Every selector is prefixed .mk- so this sheet cannot collide with the app
   stylesheet loaded alongside it.
