/* ============================================================
   Lingual — Bulletin theme tokens
   The worship bulletin is themeable per church with EXACTLY FOUR
   colors. Everything else (muted text, hairline rules, faint
   surfaces) is derived from those four via color-mix, so a church
   sets four values and the whole bulletin re-themes coherently.

   THE FOUR (override these on a .bulletin element, or per-church
   in the live bulletin via tenants.bulletin_theme):
     --bulletin-bg        page / paper background
     --bulletin-text      body text  (also the weight-only "All" bold)
     --bulletin-quote-bg  fill behind scripture quotations
     --bulletin-accent    the one pop color — headings, order labels,
                          rubric instructions, role labels, hymn
                          numbers, references, the mast ornament

   Defaults alias the global rubric-on-paper palette (tokens/colors.css)
   so an un-themed bulletin is identical to today's. The derived muted/
   rule values also default to the hand-tuned --ink-muted/--rule so the
   un-themed bulletin renders with the same computed colours as before (the
   CSS text uses var indirection, but no colour changes); a custom theme
   re-derives them from its own four colors via color-mix.
