RiseDesk — Standing Desk Configurator + Ergo Calculator + CTA

Affiliate opportunity #3 of 5 (Productivity). A value-add standing-desk landing page paired with a 30–45s CTA video. Value-add tools on the page: (1) a desk configurator — size (48/60/72"), top finish (Bamboo/Walnut/White/Black oak) with a LIVE preview tint, and frame color, with price + specs updating live; (2) an ERGONOMIC sit/stand height calculator that takes the user's height (cm/in) and typing preference and returns standing desk height, sitting desk height, monitor eye-line height and seat height, with an SVG figure. Affiliate target: Amazon / Fully-Uplift (placeholder tag links). CTA video voice: Matilda (knowledgeable, professional). Self-contained single-file HTML prototype, no BaaS. Reference media: two royalty-free standing-desk/office photos attached to this Idea.
