/*
  PresetWing site styles.

  One stylesheet, no build step, no framework, no web font, no image file. The
  design direction comes from the product brief: a compact work sheet in navy,
  warm white and one amber attention accent, with rectangular section headers,
  a quantity column and obvious unchecked, checked and attention marks. It is
  meant to read like a prop preset sheet on a clipboard, not like a card stack.

  Palette. Every text pair below was computed against its actual background
  rather than eyeballed, and the numbers are in
  ../receipts/01-deploy-2026-09-04.md. The lowest text pair on the site is
  5.85:1, which clears WCAG AA (4.5:1) at normal sizes with room.

    ink        #16233c on paper 14.67   on surface 15.42   on band 12.88
    ink-soft   #4b5875 on paper  6.66   on surface  7.00   on band  5.85
    amber-ink  #7a4a00 on paper  7.00   on surface  7.36   on tint  6.59
    paper      #fbf7ef reversed on ink 14.67

  --rule (1.44:1), --edge (2.10:1) and --amber-line (3.23:1) are below 3:1 and
  are NOT used for text and NOT used as the only carrier of any meaning. They
  are ruled lines and borders on a work sheet. Every mark in the illustration
  also carries a word, and the illustration is aria-hidden with its meaning
  written in the prose beside it.

  Light only. A second palette means a second full set of contrast
  measurements, and there is no requirement for one here.
