Replaced 33 unreadable citation markers in docs/FEATURE_PAGE_COPY_AND_FOCUS.md with named sources: Baymard Institute articles, Gartner's 2026 B2B buyer survey releases, Unbounce's 2024 Conversion Benchmark Report, Nielsen Norman Group articles, the PostHog, Linear, Sigma, monday.com and Zoho pages it describes, and docs/FEATURE_MARKETING_MATRIX.md.
Corrected claims the sources do not support: the 67 percent, seven-source and 45 percent figures come from one Gartner survey, not two; Unbounce calls 250 to 725 words the ideal SaaS word count, not the best-performing range; Zoho's pages do not use the quoted heading "Bring in your Word docs"; and the NN/g visual-design, layer-cake, similarity and conventions points now say what those articles say. Two inferences the guide had attributed to Baymard (showing several interface states, and judging a switch from a familiar product) are now marked as the guide's own reading and one participant's remark.
