/* utilities.css
   Hand-written static replacement for the Tailwind CDN build.
   Implements exactly the utility classes used across the 9 site/public/*.html
   pages (static markup + classes built in <script> template strings).
   Values follow js/theme.js (custom colors/spacing/fontSize/fontFamily/
   borderRadius) and Tailwind v3 default scales for the standard utilities.
   Custom component classes (bento-cell, sidebar, toggle-*, input-field,
   hero-*, reveal-up, etc.) stay in each page's inline <style> and are NOT
   redefined here. */
