/*
 * Vayu SMS design system.
 * Tokens are taken verbatim from README.md "Design Tokens" and the inline <style> block in the
 * .dc.html files. Bootstrap 5.3.8 supplies the grid and a few utilities; everything with a visual
 * identity (cards, badges, buttons, sidebar, tables) is defined here, because the design's 2px ink
 * borders and pill badges are not Bootstrap's look.
 */

/*
 * PALETTE: Aviatrack, not Vayu.
 *
 * The token NAMES are unchanged so none of the ~1,400 lines of rules below need editing —
 * only the values behind them. Everything is remapped onto app-theme.css so SMS reads as
 * part of Aviatrack: Aptos instead of Archivo, hairline borders instead of 2px ink, 8/10px
 * radii instead of 10/16/20, and the muted navy/blue palette instead of the high-contrast
 * ink/sky one.
 *
 * The four-step risk scale is kept as four distinguishable steps, because low/medium/high/
 * intolerable is a regulatory distinction, not decoration — it is just moved into
 * Aviatrack's quieter register.
