/* ==================================================================
   Box measuring guide — redesign v1
   Page: как-да-измерите-вложките-...-на-кутиите-v1.html

   Scoping: every content rule lives under main.bm-page.
   The few rules outside <main> (skip link, reading tape, navbar
   dropdown button, back-to-top) use .bm- classes that exist only
   on this page, so no other page is affected.

   Visual idea: a die-line drawing. Kraft board colours, dimension
   lines with end ticks under chapter headings, dashed "crease"
   lines between box types, and a measuring-tape reading bar.
   Brand tokens from style.css: --primary #AB7442, --dark #353535.
