• October 6, 2026: full fact-check pass across the guides. Heights, airflow, humidity, lighting and price figures were compared with published guidance. Figures that could not be supported were softened or removed, and every guide now shows a review date and a "Where this comes from" section.
• October 6, 2026: overlapping guides were merged into one page per topic. The old addresses redirect to the new pages.
• October 6, 2026: added the fan size and vanity lighting calculators.
