/**
 * Beyond Volatility — "Structured Swiss" Design System v6.0 (sitewide core)
 * ==========================================================================
 * Objective clarity in complex systems. Classic Swiss typography meets
 * architectural blueprints: pure white canvas, ink, graphite, 1px grid-line
 * rules everywhere, sparing accent blue, sharp corners, subtle card lift.
 * Institutional, curated, premium — an elite research firm's annual report.
 *
 * Replaces the v5.0 "Print & Terminal" brutalist system entirely.
 * Loaded globally, before the page sheets:
 *   swiss-core.css  → tokens + primitives (this file)
 *   swiss-home.css  → homepage sections
 *   swiss-pages.css → Tools case files, About, Contact, Toolkit, legal
 *   swiss-tools.css → calculator override layer (loads LAST on tool pages)
 *   swiss-blog.css  → journal treatment for posts + archives
 *
 * Class namespace: .bv-sw-*   Body scope: body.bv-swiss
 *
 * THEMING — light is default; dark is a warm, comfortable variant.
 * Every color in every swiss-* sheet goes through the tokens below, so the
 * whole site flips via:
 *   1. @media (prefers-color-scheme: dark)  — automatic
 *   2. html[data-bv-theme="dark" | "light"] — explicit override hook (wins)
 * A small JS bootstrap applies the stored choice early; the toggle itself
 * simply updates html[data-bv-theme] and color-scheme.
 *
 * TOC
 *   1. Tokens (light)
 *   2. Tokens (dark) — media query + attribute override
 *   3. Page scope, canvas, header tint, blueprint grid
 *   4. Type primitives (display, kicker, lede, meta)
 *   5. Surface primitives (rules, tags, buttons, structural cards)
 *   6. Masthead + page hero
 *   7. Index table (research-index rows)
 *   8. Data block (ink panel) + inline form
 *   9. Ticker strip
 *  10. Figures & images (grayscale reveal)
 *  11. Prose (longform / legal)
 *  12. Motion & accessibility
