/* mswx — nerd-mode design system  ·  "weather ops terminal"
 *
 * Cyberpunk / phosphor-CRT theme. Near-black base, neon accents, glow,
 * scanlines, corner brackets, monospace-forward. Built to make the
 * multi-series chart MORE legible (neon lines pop on black), not less.
 *
 * Structure: tokens → CRT chrome → header/nav → primitives (page-head,
 * panel, controls, metric, table) → new components (boot, lab, glossary,
 * models, ticker) → page-specific → responsive.
 *
 * Every legacy class name from the pre-2026-05-26 design is preserved and
 * re-skinned, so the analysis pages (stations/verify/deltas/lapse/
 * inversions/records/last-frost) re-theme without per-page edits.
