/* ====================================================================
   SnoreCare Landing Page - design system
   A fork of the portfolio landing-page template (dark variant). The section
   grammar and script.js are inherited unchanged; only the tokens, the font
   and the motif differ.

   TOKENS COME FROM THE SHIPPED APP: src/theme/colors.js in the app repo
   (page #06020E, card #130F1E, surfaceRaised #1E1B2B, track #2A2636,
   border #3A3547, text #FFFFFF, textSecondary #D4D2DA, textMuted #A9A6B2,
   primary #7A56EF, accent #B08AF5, brandLight #9B7EF7, warning #F0C86B,
   success #9BB167, glow #1B1030 -> #06020E).

   CONTRAST, measured (WCAG 2.x, python) - text pairs on the page bg #06020E
   unless stated:
     #FFFFFF  text            20.53:1  (18.84 on card #130F1E)
     #D4D2DA  textSecondary   13.72:1  (12.59 on card)   body copy
     #A9A6B2  textMuted        8.59:1  (7.88 on card, 7.05 on #1E1B2B)
     #B08AF5  accent           7.63:1  (7.00 on card)    accent words, links
     #9B7EF7  brandLight       6.57:1  (6.03 on card)    small icons
     #F0C86B  warning         12.89:1  (11.82 on card)   second accent
     #7A56EF  primary          4.31:1  (3.95 on card)    large numerals and
                                       graphics only, never small text
     #FFFFFF label ON #7A56EF  4.77:1  primary button label
     #FFFFFF label ON #6E4BE6  5.51:1  where the button gradient ends
     #06020E ink ON #B08AF5    7.63:1  ticks and icons on accent discs

   BUTTONS: the primary fill is #7A56EF with a WHITE label (4.77:1). The CTA
   gradient only ever runs DARKER than #7A56EF (to #6E4BE6, hover #6340DB), so
   the white label gains contrast across the sweep. The brand gradient
   #7A56EF -> #B08AF5 is art only (glows, rays) and never sits behind text.
