# HyperFrames HTML is the source of truth for video. A composition is an HTML file with `data-*` attributes for timing, a GSAP timeline for animation, and CSS for appearance. The framework handles clip visibility, media playback, and timeline sync. ## Approach ### Discovery (exploratory requests only) For open-ended requests ("make me a product launch video", "create something for our brand") where the user hasn't committed to a direction, understand intent before picking colors: - **Audience** — who watches this? Developers? Executives? General consumers? - **Platform** — where does it play? Social (15s), website hero, product demo, internal? - **Priority** — what matters most? Motion quality? Content accuracy? Brand fidelity? Speed? - **Variations** — does the user want options, or a single best shot? For specific requests ("add a title card", "fix the timing on scene 3"), skip discovery. For exploratory requests, consider offering 2-3 variations that differ meaningfully — not just color swaps, but different pacing, energy levels, or structural approaches. One safe/expected, one ambitious. Don't mandate this — it's a tool available when appropriate. ### Step 1: Design system If `design.md` or `DESIGN.md` exists in the project, read it first (check both casings — they're different files on Linux). It's the source of truth for brand colors, fonts, and constraints. Use its exact values — don't invent colors or substitute fonts. Any format works (YAML frontmatter, pros...
