/* ==========================================================================
   Yuliya Photography - public site styles

   Visual direction follows the reference site the client picked
   (photowithkaty.com): white background, black type, bold centred sans-serif
   headings, a photo mosaic instead of a banner, a round portrait, dense photo
   grids with tight gaps, pill buttons with a 2px outline, a dusty-rose call to
   action band and a light grey contact block.

   Mobile-first. Breakpoints: 600px, 900px, 1200px.

   No external fonts or assets are loaded, so the site makes zero third-party
   requests and no visitor data ever leaves the server.
