   Calendar — Day/Chair Grid View
   Design principles applied:
   · Chair colour appears as the column header's bottom border (3px)
   · Hour lines (09:00, 10:00) are STRONGER than half-hour lines (08:30)
   · Appointment cards use solid opaque pastel backgrounds
   · Patient name is the biggest, boldest text on every card
   · Time label aligns to the TOP of its slot = sits AT the hour line
   · Alternating subtle row tint every full hour (depth/readability)
