/* ============================================================
   michaelurquidi.com - Page layout system (Option 2)
   The spec-sheet treatment shared across every page.
   Depends on tokens.css (palette, type, scale) and site.css
   (nav, buttons, cards, footer, reveal). This file only adds
   page structure: the document-meta strip, mastheads, numbered
   section scaffold, and the page-specific blocks.
   Palette discipline: olive does the work, gold marks the one
   paid thing, purple appears once as the writing panel.
