/*
  Base styling — minimal and lightweight by design: system font
  stacks only (no web font downloads), no JS, no build step beyond
  Eleventy itself. Light/dark palettes are both defined as custom
  properties so prefers-color-scheme just swaps values, no separate
  dark-mode rules to maintain.

  Changes from the original version: added an --accent-color used
  deliberately (header rule, hover states) instead of relying on
  link-blue for everything; more typographic contrast between the
  homepage bio, post titles, and body copy; transitions on
  interactive states; focus-visible outlines for keyboard nav;
  blockquote/code styles that were previously undefined; and a
  narrow-viewport tweak so post thumbnails stack above the text
  instead of squeezing it.
