The design-style extractor now captures a site's signature color grounds and materials that a flat background-color misses: - Capture gradient background-image + backdrop-filter on buttons/cards/nav. - backgrounds[]: dominant gradient / mesh washes ranked by on-screen area (includes ::before/::after glow orbs), chroma-weighted so a small vivid brand wash outranks a large neutral scrim. - glass[]: frosted-glass panels (backdrop-filter blur) with their raw translucent fill, border, radius, shadow — ranked by area. - nav CTA capture: keep filled buttons inside <nav> (a page's primary "Sign up" / "Start for free" CTA that the old nav-drop lost), including gradient-filled CTAs whose background-COLOR is transparent. - Dedup keys for buttons/cards now include gradient + glass so a gradient/frosted variant is not collapsed into its flat sibling. - Fix: a fully-transparent fill rgba(...,0) now reports "transparent" instead of #000000 — the old bug turned every transparent wrapper into a phantom black button/card. types: ComponentStyle gains backgroundImage/backdropFilter; DesignStyles gains backgrounds[] and glass[].
