Academy v3: screenshot-verified scenes, transform-override fix, hero bean-journey slide
Test and deploy / test-and-deploy (push) Successful in 56s
Test and deploy / test-and-deploy (push) Successful in 56s
Root cause of the broken diagrams found and fixed: CSS transform animations were overriding the SVG positioning transform on the same element, throwing animated elements (beans, flames) to the canvas origin — the bean/flame helpers now split position (outer group) from animation (inner group). Every scene was then rendered in headless Chromium and screenshot- inspected, with fixes applied and re-verified: drying-scene label collision, RoR ideal-line label overlap, first-crack dot off the curve, composition bar stagger orphaning its labels, moka flame hidden behind the base. New opening slide (user request): 'The whole journey, in one bean' — a large bean on a 14-second loop living the full roast (heat in, drying steam out, green→yellow→brown, pressure swell, crack) synced to a stage timeline with a riding marker; narrated like the rest.
