Assemble a silent, music-led 3-world product-tour ad — trim and hard-cut-concat the per-world WIDE-arrival + top-down-macro clips, composite the HTML/Playwright brand end card ("FIND YOUR DAILY." + handwritten scent labels + arrows) over an AI flat-lay background, and mux one music bed into a 720x1280 web master. FREE, deterministic assembly (Playwright + PIL/HTML + FFmpeg); the recipe supplies the config and gates the paid clip/background/music calls.

We are designing the HTML template for our multiworld product tour end card overlay. The visual style calls for a bold, high-impact headline reading 'FIND YOUR DAILY.' What font family and font weight must be assigned to this headline element in the HTML CSS?
| Checked | Without skill | With skill |
|---|---|---|
| Headline CSS font-family is set to Inter | Missed | Passed |

Assemble a silent, music-led "multi-world product tour" ad (≈27s, 9:16) — a tour of three distinct "third-place" worlds (chosen per video), one per product/variant, that lands on a Pinterest-style brand end card. Each world is a two-shot pair: a ~4.5s WIDE kinetic-calm ARRIVAL (the environment dominates, the product stays small) hard-cutting to a ~3.5s top-down MACRO product MOMENT (the sealed product nested with its companion prop). Variant identity is carried by the world + companion prop, not by product color. No VO, no captions in the scenes — one music bed carries the whole thing.
This capability is the FREE, deterministic assembler. The paid steps — the six per-world clips, the AI flat-lay end-card background, the ElevenLabs music bed — are separate capabilities (see the gap below for the clips); the recipe orchestrates and gates them.
The calling recipe asks the user these before any paid step; this capability only assembles what they produced. The worked example (Primally Pure) values are examples, never defaults.
