/* Care Chart, "Neon Material" look: an imagined operating system that is half Google's
   Material Design and half cyberpunk.

   From Material: surfaces that sit at different heights with layered shadows, a solid
   app bar, uppercase buttons with a ripple when pressed, underlined text fields, tabs with
   a sliding indicator, thin linear progress, and a "snackbar" for notices.
   From cyberpunk: near-black night, neon edges that glow, corners cut off at an angle,
   faint scanlines and a city grid, monospaced readout labels, and a chromatic "glitch"
   edge on the app's title.

   Night is the native mode; Day keeps the neon on white Material paper. Schemes are four
   neon pairings. Chosen per device in Settings → This device → Look; app.js sets
   data-skin="neon" and data-scheme on <html>. Everything sits inside one
   :root[data-skin="neon"] block (CSS nesting), so this file changes nothing else. */
