/* BeargrassPublishing v2 — bands.css.

   Owns the banded layout primitive: the .band wrapper, scene
   background with desktop/mobile dual-object swap, the hero band
   variant (eyebrow + headline + deck + conversation overlay), and
   per-mode treatments (Paper cream card / Night dark card / Open
   no-card frosted-strip cinema).

   Architecture:
     <section class="band band--hero">           hero band (one per page)
       <div class="band__bg">
         <object .band__bg-desktop ...>
         <object .band__bg-mobile ...>
       </div>
       <header class="band__content band__content--hero">...</header>
     </section>

     <main class="banded-main">
       <section class="band band--content" data-band-ordinal="N">
         <div class="band__bg">...</div>
         <div class="band__content">...content fragment...</div>
       </section>
       ...repeat per band...
     </main>

   Three modes (Paper / Night / Open) handled at the .band__content
   level. No !important.
