/*
  Carmeci Academy — house style
  Copyright © 2024-2025 Carmeci Academy. All Rights Reserved.

  A quiet, editorial dark theme: warm charcoal canvas, Garamond display
  type, small tracked capitals for labels and navigation, off-white
  buttons with a soft gold glow, hairline borders and a faint film grain.

  Linked at the END of every page's <head>, after the page's own <style>.
  The Tailwind Play CDN injects its utilities at runtime (after this file),
  so every rule that has to beat a utility class is written as `html .x`
  (one extra element in the selector) or uses !important where Tailwind
  sets the same property on the element itself.

  Colours for utility classes come from carmeci_theme.js.
  Opt out per element with class="ca-plain" (no restyling of buttons).
