Plume Titanium Knife Landing Page

Four-section cinematic product landing page for a titanium-core knife on pure black: full-bleed videos behind white Archivo and Inter editorial type, a hero collage, a recipe section with animated callout lines and a closing essentials CTA. The third section is a native CSS sticky scroll track where a video plays once at 2x, then three knife stills cross-fade with per-letter headlines as you scroll. One HTML file with vanilla JS, a mobile menu and stacked layouts for phones and short screens.
