   Brand notes:
     - Teal #39bcbe + dark teal-navy #004e65 are FCL's real accent/heading
       colors, pulled from flatheadcountylibrary.org's live computed styles
       (not guessed).
     - Raleway (variable weight, self-hosted in ./fonts/) is the real site's
       heading font, and a free Google Font (OFL-licensed), safe to
       redistribute in this document.
     - The site's body-copy font, Eagle-Book, is a separately-licensed
       custom font — NOT embedded here since Frostbyte doesn't hold a
       redistribution license for it. Body text uses a plain serif fallback
       instead; swap in Eagle-Book only if/when FCL confirms Frostbyte can
       use it here.
   Inlined into each HTML file at build time so the PDFs are self-contained.

/* -------------------- 15. Dark mode -------------------- */
/* Applied via data-theme="dark" on <html>, set pre-paint by the inline
   no-flash <head> script and toggled by scripts/ui.js. Re-points the same
   semantic vars used everywhere above, so navbar/content/footer all pick up
   dark styling automatically without per-selector overrides.

   Color inventory (light → dark), decided before writing any rules below:
     --teal        #39bcbe → #4fd0d2  accent (brand mark, note/bundle borders)
     --teal-dark   #004e65 → #7fd4e6  HEADINGS/TEXT role (mast, h2, item

                                      because most of its ~9 uses are text,
                                      not background

     --gold-ink    #96721f → #d9ad55  kick labels, monthly status-pill text
     --ink         #16232b → #e8edf0  body text
     --ink-soft    #52646d → #9db0ba  muted/secondary text
     --paper       #ffffff → #10181d  page background
