/*
 * Dark theme for the Health & Life Science Solution Bootcamp.
 *
 * Honkit's default theme already ships a "Night" mode (body class
 * `.color-theme-2`, toggled via the "Aa" button and set as the default in
 * book.json). This stylesheet polishes that Night mode and styles the bits the
 * stock theme doesn't handle well in dark — Mermaid diagrams, glossary-term
 * links, tables, code blocks, and blockquotes. Everything is scoped to
 * `.book.color-theme-2`, so the White and Sepia themes are untouched.
