   Rivetira — Stylesheet
   Enterprise data-visualization system. Pure CSS, no framework.

   STRUCTURAL RULE: every section sits on the one canvas (--bg-base). Sections
   are separated by whitespace alone — never by borders, rules, <hr> or tone
   steps. Hairlines only ever appear INSIDE components (card edges, chart
   gridlines, table row rules, list dividers). Depth is a hairline plus one
   opaque tonal step; there are no gradients, shadows, glows or blur.
