/* Originally ported verbatim from design/mockup/index.html's inline <style>
 * block -- see design/mockup/NOTES.md for the design rationale behind the
 * tokens, type pairing, and severity ramp below. This file has since
 * diverged from the static mockup based on real usage of the live app
 * (single-day navigation, unread indicators, the aesthetic pass documented
 * inline below); the mockup is a historical reference, not the source of
 * truth, going forward.
 *
 * Hallmark · route: custom (bespoke) · structure: day-strip nav + deterministic day-part forecast table + bottom tab bar
 * idea: "a spreadsheet you'd actually trust at the helm — hairlines and tabular figures, not a weather-app hero"
 * paper: oklch(97% 0.006 235) / oklch(15% 0.012 235) · accent(severity): warm ramp, monotonic L against rising chroma in both schemes · accent(neutral): oklch(40% 0.05 235)
 * display: Space Grotesk · body: IBM Plex Sans · data: IBM Plex Mono
 * axes: light+dark(paired) / geometric-sans / neutral (severity ramp is functional, not decorative) · gates: all-pass · studied: no
