/* ============================================================
   site.css — shared across every page
   Melissa L. Lawson Design

   What lives here: design tokens, reset, page shell, nav +
   hamburger, buttons, the Lab CTA band, footer, reveal animation.

   What stays in each page's own <style> block: anything specific
   to that page — hero layouts, article typography, post cards,
   palette pickers, timelines.

   Load order matters. In every page, this file is linked BEFORE
   the page's <style> block, so page rules win when they overlap.
