/* ═══════════════════════════════════════════════════════════════════
   base.css — shared design foundation for all pages
   Extracted from the homepage (index.html) inline <style> block.

   Pages should:
     1. Load header.css (shared nav)
     2. Load base.css (this file)
     3. Load the homepage Google Fonts triplet (Newsreader, Plus Jakarta
        Sans, Caveat)
     4. Add a page-specific <style> block for layout/sections only.

   index.html now also loads base.css — this is the single source of
   truth for tokens, reset, utilities, buttons, and footer. No drift
   to maintain.
   Note: `.lede` is a top-level default here; index.html scopes `.lede`
   per section (e.g. `.hero-split .copy .lede`, `.paths-head .lede`).
   Section-scoped rules in index.html override this default, which is
   intended.

   Do NOT add dark-mode CSS here — the design is intentionally
   light-only. The header is dark-mode aware via header.css's own
   :root[data-theme="dark"] block; that's separate.
