/*
 * MBA Deadlines Calendar — F1GMAT
 * Colours and type derive from the F1GMAT APU theme tokens (the --fg-*
 * variables defined in the theme's style.css :root). Each --mbacal-* token
 * reads the matching --fg-* variable with the theme's exact hex as a fallback,
 * so the calendar follows the house palette when the theme CSS is loaded and
 * still renders correctly in isolation. Fonts match the theme: Georgia serif
 * for prose and figures, Arial for UI labels and meta. One reserved urgency
 * colour (#C1440E) marks a deadline day; the theme has no token for it.
