Build a 14-second motion design product film in 16:9 (1920x1080, 30 fps) for my app {{{NAME}}}, which {{{WHAT_IT_DOES}}}.
Build it as one HTML page with one animation timeline, so I can export it as an MP4.

Look: light grey-green background with a soft grid, white cards with thin borders, one brand colour {{{HEX}}}, one clean sans-serif font.

The text builds word by word: "{{{HOOK_QUESTION}}}" / "{{{NAME}}} {{{STEP_1}}}, {{{STEP_2}}}, and {{{STEP_3}}} for you." / "{{{RESULT}}}."
Scene 1: the hook question, big and centred.
Scenes 2 to 4: one card shows each step. The card from one step becomes the object of the next step.
Scene 5: the result with a small "done" stamp.
Scene 6: logo, name and "{{{TAGLINE}}}".

Rules: the camera never stands still. Every move is eased. Key words are in the brand colour, the rest stays dark.
