/* =========================================================
   Base styles for the M. Nawaz Sulaiman card
   1. Page basics
   2. Card frame (mobile first)
   3. Centred profile layout
   4. Tablet  (card 600px+)
   5. Desktop (card 900px+)
   6. Share dialog + toast
   7. Reduced motion

   The card uses a container query: it reacts to the width of
   .stage, so the layout adapts on phone, tablet and desktop.
   Colours and fonts are set in card.css.
