/* ══════════════════════════════════════════════════════════════
   SHARED DESIGN SYSTEM — site.css
   Loaded by every page. Contains only what is genuinely identical
   (or safely unifiable) across pages. Page-specific <style> blocks
   load AFTER this file, so any page-specific override further down
   the cascade still wins — this file is a safe base, not a lock-in.

   Deliberately NOT extracted here (left page-specific — see the
   Phase 1 audit for why): custom cursor (#cur/#cur-ring — 3 real
   visual variants across the 7 pages), #bg-canvas particle system
   (index.html uses a connected-node algorithm, about/members use a
   simpler free-floating-dot algorithm — different code, not just
   different constants), and .btn-primary/.btn-secondary (three
   different .btn-secondary visual treatments currently share that
   one class name). Unifying any of those would be a visual redesign,
   not a refactor — flagged separately rather than done silently.

   REUSABLE IN-PAGE SECTION NAV — Phase 3
   Shared by members.html (.section-nav) and prompts.html's category
   nav. Full-size tile grid on load / while near top of page;
   scrolling past ~150px adds .compact — desktop/tablet becomes a
   single-row pill bar, mobile becomes a "☰ Jump to section" toggle
   + dropdown. Scrolling back above the threshold removes .compact.
   The current section's tile gets .active via IntersectionObserver.
   See site_initSectionNav() below. Each page keeps its own full-size
   tile appearance (colors, sizes, copy) in its own <style> block —
   this only supplies the .compact/toggle/dropdown mechanics.
