/* GEM — the sign-in gate on a guide PDF download (2026-10-12; was the sign-up invitation of
   2026-10-11). Loaded on the patient-education article pages only, after styles.css and
   guides.css. Site tokens only; no backdrop blur (a translucent purple tint), no animation.
   The card matches the video pages' "Continue Watching" prompt: purple ground, gold rule along
   the top, white heading, a light-gold button, "Already a member? Log in" in lavender and white.
   Pairs: heading white on --purple #3A2A66 12.3:1 / on --purple-deep #2E2150 14.5:1; button
