/*
 * WORKDAYS: the tool's own components, styled in the site's design language (7 Oct 2026, on the UltraCompress Pro
 * template, after PaletteSnape). Base: /libs/site-pages.css (tokens, Inter and Space Grotesk, buttons, theme toggle,
 * focus rings) and /libs/shared-nav.css (the site's header and footer). This file holds only what the tool itself
 * needs: the toolbar with the status pill and the six pill tabs, the cards, the forms and chips, the result boxes
 * with their stat tiles and tables, the calendar, the holiday, saved and history lists, the work week rows, the
 * toggles, the confirmation window, the toasts, the print layout and the information sections. Light is the default;
 * dark applies when <html> has no data-theme.
