/* =============================================================================
   StarCraft: The Board Game — Setup & Reference Utility
   Styled after Fantasy Flight's rulebooks for the core game (2007) and Brood War (2008):
   · interior pages of pale scuffed steel inside a dark hull frame with a red keyline and
     crimson castellated plates top and bottom (every page, Base p.2–48; BW p.2–20)
   · heavy blocky uppercase headings (the books set them in "Savings Bond"; here Squada One, thickened)
   · black grid sidebars with lime headings (Base p.6, 7, 11, 13, 17) and black "Tip" boxes (Base p.13)
   · the green page-number screen in its bevelled steel frame (every page) → setup step numbers
   · hex order tokens, silver standard and gold special (Base p.20–21) → section marks, player buttons
   · each faction's worker or transport token (Base p.5) → faction chips
   · the cover's dark-red "Rules of Play" band (Base p.1, BW p.1)
   Palette sampled from the rendered pages: page #e2e9ed, text #262428, heading ink #19171b, hull red #801018,
   keyline #d22b18, frame #1d222b, sidebar black #0c1410, sidebar lime #a9ca6a, page-number screen #003018.
