/* Claero Dynamics — site stylesheet.
 *
 * Palette C1 "Morning Air" from .claude/skills/claero-design/SKILL.md — the READING-screen
 * palette, which is what a website is. The dashboards' A1 signal-orange is deliberately NOT
 * used here: the two accent families are an explicit design decision (Blake, 2026-07-27),
 * and measuring and reading are different modes. What carries across is the grammar — the
 * type scale, the tabular figures, the value+unit treatment — not the hue.
 *
 * Type scale is the app's: 12 / 14 / 17 / 22 / 28 / 40 / 64.
 * Display face is Avenir Next Condensed Demibold, the condensed-numeral motif; it ships with
 * macOS and iOS, so no webfont is loaded and no external request is made.
