/*
 * FERTILE: the tool's own components, styled in the site's design language (7 Oct 2026, on the UltraCompress Pro template,
 * after the Life Discipline Tracker). 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 fertility colours (period red, three greens for the fertile window, the ovulation green), the toolbar with the status
 * pill and the pill tabs, the dashboard's cycle ring, week view and event lists, the month calendar and its legend, the Log
 * card with its segmented tabs, choice buttons, symptom grid, mucus scale and tables, the Insights tiles, chart boxes and
 * due-date result, the Settings switches, PIN rows and share box, the windows, toasts, the information sections and a print
 * sheet for the Insights report. Light is the default; dark applies when <html> has no data-theme.
