/*!
 * enw-tools.css — the public /book-tools/ section.
 *
 * Loaded last, after the shared sheets (a page opts in with $ebnExtraCss), so
 * its rules win the ties they need to without editing the design system.
 *
 * Everything here is drawn from the tokens in enw.css and enw-palettes.css, so
 * the nine app palettes and the light/dark switch reach these pages for free:
 * there is not one literal colour below except the two used to fake a
 * transparent zero-shadow, and nothing here has an opinion about the palette.
 *
 * The layout is a two-pane "workbench": a menu of tools pinned beside the panel
 * the reader is using. On a phone the menu becomes a horizontal scroller above
 * the panel, because a fixed sidebar on a 360px screen is a sidebar that has
 * eaten the page.
