/* ==========================================================================
   Northstar Research Coverage: the product theme for Case Study 01 (Global Research Coverage Platform).
   One portfolio design system, multiple product expressions: the portfolio page keeps the site's
   tokens, and everything inside a recreated product frame (.nls) uses this restrained product
   identity: light, global and precise. A white masthead, deep indigo type, a cool blue for
   interaction, pale blue and lilac surfaces, and status that always carries a word, never color
   alone. The interface is a concept reconstruction: same workflow and reasoning as the original
   work, with its own composition (a segmented four-step progress bar, back links above the title,
   a footer action bar, requirements grouped by item, a review side panel, a bottom-sheet save
   prompt). Product frames stay light in both site themes, like a real product screenshot.
   Shared by research-coverage*.html and prototype/research-coverage.html. Frames adapt to their own
   width (container queries), so a frame stays legible on a phone.
