   site.css — baseline stylesheet for parsonwebsite
   ==========================================================================
   Migrated from inline <style> in templates/partials/head.php (pws-9at).
   Naming conventions per ADR 0004:
     l-*   layout primitives
     c-*   reusable components
     u-*   small utilities
     is-*  state classes

   Color token system (pws-pri):
     All colors reference --color-* custom properties with hardcoded
     fallbacks that match the original light-mode appearance.  Tokens
     are defined on :root (light), then overridden in three theme
     blocks: soft-dark, manual dark, and true-black (OLED).
