/* ==========================================================================
   Recordatio - Mobile-first stylesheet
   --------------------------------------------------------------------------
   Design approach (user-centric, mobile-first):
   1. Styles are written for small screens (phones) FIRST. Larger breakpoints
      (tablet >= 700px, desktop >= 1024px) progressively ENHANCE the layout
      using min-width media queries, instead of the old approach of designing
      for desktop and squeezing things down.
   2. Every interactive element (links, buttons, checkboxes, form fields)
      respects a minimum touch target of ~44x44px, per WCAG / mobile HIG
      guidance, so it's comfortable to tap on a phone/tablet.
   3. Form inputs use font-size: 16px (or larger) to prevent iOS Safari from
      automatically zooming in when a field is focused.
   4. Data tables collapse into stacked "cards" on narrow screens (see the
      ".table-responsive" rules) so users don't have to scroll horizontally
      to read appointment/client/reminder data on a phone.
   5. The top navigation collapses into a hamburger-triggered menu below the
      tablet breakpoint, and expands into a normal horizontal bar on larger
      screens (see nav.js for the toggle behaviour).
