   ----------------------------------------------------------------------------
   The one stylesheet for the whole app. Warm scrapbook / yearbook look.
   Built for a 375px-wide phone first, then it simply centers on bigger screens.

   COLORS: don't change colors here. They come from config.php -> themes and
   are printed as CSS variables (--bg, --card, --accent, --accent2, --text)
   at the top of every page by includes/layout.php.

   Sizes: every button and form box is at least 44px tall, so it's easy to tap.
