/*
  Artha — execution desk.

  Typography
  ----------
  Figtree for the interface. Rounded terminals and near-circular bowls, so it
  reads warm rather than clinical at the small uppercase sizes this page leans
  on. Chosen over the obvious geometric rounds — Poppins, Inter, Space Grotesk —
  precisely because those three are the house style of every generated dashboard.

  DM Mono for every number, with tabular figures forced on. Round counters to
  match Figtree, and unambiguous digits: numerals here are scanned down columns,
  not read in sentences, so they must align to the pixel.

  Both fall back to a system stack. If the font host is unreachable the page
  keeps its layout and loses only the personality.

  Restraint
  ---------
  Near-monochrome. One accent — amber, for cost — used only where it carries
  meaning, plus two semantic colours that appear on maybe four elements each.
  Rules are hairlines and mostly absent; space does the separating. There are no
  card shadows, no gradients, no rounded corners, and no icon anywhere.
