icon+border, avatar with status-colored ring, date/time row, empty state
- Calendario: card-wrapped TableCalendar with custom CalendarStyle (blue
selected/ring today), day header card with date box + occupied/available
stat pills, slot cards with colored strip and time badge instead of
gradient circles
- Perfil profesional: gradient banner header with profession pill + camera
overlay, section cards with icon+title, payment method chips (animated)
instead of checkboxes, schedule rows with colored active/inactive dots,
theme-aware colors throughout (respects dark/light mode)
