/* ARYS Intelligence — shared site layer (2026-09 redesign).
   Loaded LAST on every page, after the page's own inline <style>. It carries the site-wide look:
   Source Serif 4 headings + Source Sans 3 body on the original ink / paper / copper palette,
   light cream heroes, pill buttons, and the shared header + footer (injected by
   deploy/apply-shell.py). Page-specific layout stays in each page's inline styles. */
