/*
 * find.css: the in-document find bar (js/reader/find.js) and its highlights.
 *
 * Uses the theme tokens from tokens.css, always loaded with the shell (input, icon buttons and marks
 * match the shell's search box, .icon-btn and search highlights).
 * The bar is sticky at the top of the text pane and overlays the content (negative bottom margin),
 * so opening it never pushes the text down.
 *   --find-top   sticky offset (e.g. the header height when the document itself scrolls)
