/* Reflections: stylesheet
 *
 * A self-contained design system, written for this app rather than inherited
 * from a framework. Bootstrap's stylesheet is no longer loaded at all: the
 * handful of its classes the markup uses (btn, form-control, progress and
 * visually-hidden) are implemented here, so the interface speaks one visual
 * language instead of a framework's defaults with patches on top.
 *
 * Contents:
 *   1. Design tokens, light then dark
 *   2. Reset and typography
 *   3. Layout shell: header, navigation, menus
 *   4. Controls: buttons, forms, progress, messages
 *   5. The writing view: model tabs, sections, starters, editor, sidebar
 *   6. The library and the reading view
 *   7. Empty states and dialogs
 *   8. Small screens
 *   9. Print, which is a first-class view rather than a stripped screen
 *
 * Bootstrap Icons is still loaded, purely for glyphs; it carries no layout.

/* ========================================================== 9. Print ======
   Printing is a first-class view, not the screen layout with parts hidden.
   app.js builds a semantic document into #printRoot whenever the practitioner
   prints (Ctrl+P, the Print buttons, or the browser's Print command), and this
   block is the only thing that decides how it looks.

   Two failure modes are designed out here:

   1. A dark page. If the operating system or browser is in dark mode the page
      canvas can be printed dark, which turned light text into a faint outline
      once the background was dropped. Colour scheme is therefore forced to
      light for print, with a white canvas and black text stated explicitly.
