/*
  Oppward design tokens.
  Direction (docs/BRAND.md): deep ink base, an earned money-green accent, warm
  off-white paper tones, one alert color for deadlines. Editorial type contrast.
  Numbers are the hero of this product, so the body/number face carries real
  tabular figures (Archivo, feature "tnum" enabled below).

  Theme model: dark "ink" is the primary voice (ambient, premium, lets the green
  glow land) with light "paper" bands used deliberately for tonal contrast between
  sections, editorial-magazine style, not a flat single-color page. Both a true
  light theme (prefers-color-scheme / [data-theme]) and the alternating in-page
  bands are built from the same semantic tokens below.

  NEVER use filter: blur() or backdrop-filter: blur() anywhere in this system --
  it breaks headless rendering for the video pipeline and screenshot QA. Use
  radial-gradient soft shapes for ambient/glow effects instead.
