/* Kaze — kaze.build
   One tone (--h hue, --c chroma) drives the product's colour: the window's
   backboard, the ink and the sheen on paper. Change data-tone and it follows.

   Colour is the product's, so the page itself is neutral: four layers, each
   a clear step from the next — the page (near-white, a whisper of grain) ›
   the desktop the window sits on (a deep, saturated wallpaper in the tone,
   lit by soft blooms) › the window (the pastel backboard) › its paper
   (white). The site's own furniture (nav, sections, buttons) stays on the
   neutral page in ink; the tone appears where Kaze appears. */
