/* ==========================================================================
   Bathroom Organization — main stylesheet
   Design system: tokens, typography, components, layouts, utilities.
   No external dependencies. No remote fonts. No image files. Mobile-first.

   Look: a calm, uncluttered room. Warm-white page, white surfaces, deep teal
   for everything interactive, soft mist panels and a little sand, stone and
   blush. Three recurring motifs, all plain CSS:
     1. Soft frame — images sit in a white mat with rounded corners and a
        hairline edge.
     2. Rail line  — headings and page headers rest on a hairline with a
        short eucalyptus bar at its start.
     3. Tile dots  — list bullets and step numbers are small rounded tiles.

   Contrast reference (WCAG 2.1, calculated from relative luminance):

     blush text #8a4a36 on white / blush tint #f8eee8 ............ 6.7 / 5.9:1
     form border #72837e on white / warm white / mist (non-text) . 4.0 / 3.8 / 3.5:1
   Eucalyptus #7fa99b, sage #a9c4b8, sand #d9c9ad, sand shade #b9a27a,
   stone #e7e2d8 (on light surfaces) and blush #e0b3a2 are decoration only —
   borders, bullets, rail lines — and never carry text.
   Focus ring: 3px charcoal on light surfaces (12:1), 3px stone on the deep
   teal footer (7.5:1), always with a 2px offset.
