/*
 * Muonjaro Planner Styles
 *
 * A clean and professional layout with subtle colour accents for each pen. The
 * design uses a card-based structure to separate functional sections. It
 * adapts gracefully to smaller screens via responsive flexbox and stack
 * behaviours. Colours for pens are assigned via CSS variables on each
 * button, allowing quick adjustments to match official pen colours.
