/* =========================================================
   Selina Chu — Portfolio home page

   Units: rem everywhere (1rem = 16px at the browser's default text size),
   except
   • illustrations drawn in fixed artwork coordinates and scaled as one picture by JS
     (hero girl, bio shapes, card mockups, About-me girl, falling shapes) –
     they stay px so their parts never drift apart;
   • 1–2px hairlines (borders, outlines).

   Breakpoints (rem, so they follow the browser's text size; js/main.js uses the same):
     Phone    ≤ 37.4375rem  (~320–599px)
     Tablet   37.5–63.9375rem (~600–1023px)
     Desktop  ≥ 64rem        (1024px and up)
