   HOW TO EDIT THIS FILE — read this first
   ============================================================
   Everything you'd want to change lives in the ":root" block
   right below. Change a value there and it updates EVERYWHERE
   that color/font/spacing is used on the site. You almost never
   need to touch anything past the ":root" block unless you want
   to change a specific component's layout.

   QUICK RECIPES:
   - Change the pink shade           -> edit --sakura-pink
   - Make panels more/less square    -> edit --radius (0 = sharp)
   - Change the page background      -> edit --bg-page
   - Change panel title bar color    -> edit --title-bg
   - Swap the heading font           -> edit --font-display
   - Make borders thicker/thinner    -> edit --border-w
