   Pure CSS, no build step. Mobile-first; breakpoints: 640 / 960 / 1280.

   CLASS INDEX (reuse these on every page; BEM-ish: block, block__part, block--variant)
   --------------------------------------------------------------------------
   Layout     .container  .container--narrow  .section  .section--tight

              Section spacing: ONLY .section sets vertical padding, via the
              --section-y variable. Change spacing by overriding --section-y
              (.section--tight does) - never add padding-block to a section.
