   Tokens are mirrored into Tailwind via build/tailwind.config.js,
   so `text-brand-accent`, `font-serif`, etc. resolve to these values.
   Class names (spm-*, tour-*, vertical-tab-btn, reveal-*) are unchanged so
   spm.js continues to work.
   ========================================================================== */

/* --------------------------------------------------------------------------
   HOW THE COLORS WORK (read this first)
   1. The tokens below are the whole palette. Everything else looks them up.
   2. A "panel" is a big rounded section. By default it is light.
   3. Add  spm-panel--dark  to a panel and it turns navy. It does this by
      swapping the text tokens (headings white, body light grey), so any text
      inside automatically becomes readable on navy.
   4. Add  spm-panel--light-boxes  as well and the cards inside stay light
      stone-colored; they swap the text tokens back to dark for themselves.
   Current setup (see the class list on each <section> in the HTML):
      Platform, FAQs   spm-panel--dark + spm-panel--light-boxes
      Industries       spm-panel--dark only (dark glass box; its three
                       "at a glance" tiles are stone-colored like the cards)
      Accessibility, Contact   plain light panel
   To change a section's look, add or remove those classes. To change the
   card color for all navy sections at once, edit ".spm-panel--light-boxes .spm-box".
