/* ===========================================================================
 * Glide theme
 *
 * A modern, clean mdBook theme. This file is loaded via `additional-css`, so it
 * layers on top of mdBook's default stylesheets (variables/general/chrome) and
 * overrides only what's needed — keeping all of mdBook's structural CSS intact
 * (sidebar positioning, the .hidden helper, the keyboard-help popup, etc.).
 *
 * Two palettes: "light" (default) and "navy" (our dark), ported from the design
 * reference. Markup hooks added by index.hbs / glide.js are prefixed `glide-`.
