/* Sharpe & Clear — Level I sales page, version 2 (/level-1/). Dark (navy) like the rest of the site: colours come from
   the variables of site.css (--bg, --card, --card2, --line, --ink, --ink2, --ink3, --sky, --teal, --good…) plus the
   few tokens below. Load after site.css and nav.css. Every class starts with "lp-". Phone first.
   No inline style, no url(), no external file (CSP style-src 'self').
   The sky→teal gradient fills shapes and buttons only, with navy text on it. The live demos sit on white cards
   (demo2.css, .d2-light) so they stand out on the navy page, like the light app in the screenshots. */
