 ## 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, prose, tables — just extract the values).
+
+If it names fonts you can't find locally (no `fonts/` directory with `.woff2` files, not a built-in font), warn the user before writing HTML: "design.md specifies [font name] but no font files found. Please add .woff2 files to `fonts/` or I'll fall back to [closest built-in alternative]."
+
+If no `design.md` exists, offer the user a choice:
+
+1. **User named a style or mood?** → Read [visual-styles.md](./visual-styles.md) for the 8 named presets. Pick the closest match.
+2. **Want to browse options visually?** → Run the design picker: read [references/design-picker.md](references/design-picker.md) for the full workflow. This serves a visual picker page. The user configures mood, palette, typography, and motion in the browser, then copies the generated design.md and pastes it back into the conversation.
+3. **Want to skip and go fast?** → Ask: mood, light or dark, any brand colors/fonts? Then pick a palette from [house-style.md](./house-style.md).
+
+**design.md defines the brand. It does not define video composition rules.** Those come from [references/video-composition.md](references/video-composition.md) and [house-style.md](./house-style.md). Use brand colors at video-appropriate scale — not at web-UI opacity.
+
+### Step 2: Prompt expansion
+
+Always run on every composition (except single-scene pieces and trivial edits). This step grounds the user's intent against `design.md` and `house-style.md` and produces a consistent intermediate that every downstream agent reads the same way.
+
+Read [references/prompt-expansion.md](references/prompt-expansion.md) for the full process and output format.
+
+### Step 3: Plan
+
 Before writing HTML, think at a high level:
 
 1. **What** — what should the viewer experience? Identify the narrative arc, key moments, and emotional beats.
 2. **Structure** — how many compositions, which are sub-compositions vs inline, what tracks carry what (video, audio, overlays, captions).
-3. **Timing** — which clips drive the duration, where do transitions land, what's the pacing.
-4. **Layout** — build the end-state first. See "Layout Before Animation" below.
-5. **Animate** — then add motion using the rules below.
+3. **Rhythm** — declare your scene rhythm before implementing. Which scenes are quick hits, which are holds, where do shaders land, where does energy peak. Name the pattern: fast-fast-SLOW-fast-SHADER-hold. Read [references/beat-direction.md](references/beat-direction.md) for rhythm templates.
+4. **Timing** — which clips drive the duration, where do transitions land, what's the pacing.
+5. **Layout** — build the end-state first. See "Layout Before Animation" below.
+6. **Animate** — then add motion using the rules below.
 
-For small edits (fix a color, adjust timing, add one element), skip straight to the rules.
+**Build what was asked.** A request for "a title card" is not a request for "a title card + 3 supporting scenes + ambient music + captions." Every scene, every element, every tween should earn its place. If additional scenes or elements would genuinely improve the piece, propose them — don't add them.
 
-### Visual Identity Gate

 <HARD-GATE>
-Before writing ANY composition HTML, you MUST have a visual identity defined. Do NOT write compositions with default or generic colors.
-
-Check in this order:
-
-1. **DESIGN.md exists in the project?** → Read it. Use its exact colors, fonts, motion rules, and "What NOT to Do" constraints.
-2. **visual-style.md exists?** → Read it. Apply its `style_prompt_full` and structured fields. (Note: `visual-style.md` is a project-specific file. `visual-styles.md` is the style library with 8 named presets — different files.)
-3. **User named a style** (e.g., "Swiss Pulse", "dark and techy", "luxury brand")? → Read [visual-styles.md](./visual-styles.md) for the 8 named presets. Generate a minimal DESIGN.md with: `## Style Prompt` (one paragraph), `## Colors` (3-5 hex values with roles), `## Typography` (1-2 font families), `## What NOT to Do` (3-5 anti-patterns).
-4. **None of the above?** → Ask 3 questions before writing any HTML:
-   - What's the mood? (explosive / cinematic / fluid / technical / chaotic / warm)
-   - Light or dark canvas?
-   - Any specific brand colors, fonts, or visual references?
-     Then generate a minimal DESIGN.md from the answers.
-
-Every composition must trace its palette and typography back to a DESIGN.md, visual-style.md, or explicit user direction. If you're reaching for `#333`, `#3b82f6`, or `Roboto` — you skipped this step.
+Before writing ANY composition HTML — verify you have a visual identity from Step 1. If you're reaching for `#333`, `#3b82f6`, or `Roboto`, you skipped it.
 </HARD-GATE>
 
-For motion defaults, sizing, entrance patterns, and easing — follow [house-style.md](./house-style.md). The house style handles HOW things move. The DESIGN.md handles WHAT things look like.

 1. **Identify the hero frame** for each scene — the moment when the most elements are simultaneously visible. This is the layout you build.
 2. **Write static CSS** for that frame. The `.scene-content` container MUST fill the full scene using `width: 100%; height: 100%; padding: Npx;` with `display: flex; flex-direction: column; gap: Npx; box-sizing: border-box`. Use padding to push content inward — NEVER `position: absolute; top: Npx` on a content container. Absolute-positioned content containers overflow when content is taller than the remaining space.

 ## Typography and Assets
 
-- **Fonts:** Just write the `font-family` you want in CSS — the compiler embeds supported fonts automatically. If a font isn't supported, the compiler warns.
+- **Built-in fonts:** Write the `font-family` you want in CSS — the compiler embeds supported fonts automatically.
+- **Custom fonts:** If design.md names a font that isn't built-in, the user must provide `.woff2` files in a `fonts/` directory. If missing, warn before writing HTML. When files exist, add `@font-face` declarations pointing to the local files.
 - Add `crossorigin="anonymous"` to external media
 - For dynamic text overflow, use `window.__hyperframes.fitTextFontSize(text, { maxWidth, fontFamily, fontWeight })`
 - All files live at the project root alongside `index.html`; sub-compositions use `../`
 
 ## Editing Existing Compositions
 
-- Read the full composition first — match existing fonts, colors, animation patterns
+- **Read actual files, don't guess.** When editing, extending, or creating companion compositions, read the existing source. Don't reconstruct hex codes from memory. Don't guess GSAP easing patterns. The composition IS the spec — extract exact values from it.
+- Match existing fonts, colors, animation patterns from what you read
 - Only change what was requested
 - Preserve timing of unrelated clips

+### Design Adherence
+
+If a `design.md` exists, verify the composition follows it after authoring. Read the HTML and check:
+
+1. **Colors** — every hex value in the composition appears in design.md's palette section (however the user labeled it: Colors, Palette, Theme, etc.). Flag any invented colors.
+2. **Typography** — font families and weights match design.md's type spec. No substitutions.
+3. **Corners** — border-radius values match the declared corner style, if specified.
+4. **Spacing** — padding and gap values fall within the declared density range, if specified.
+5. **Depth** — shadow usage matches the declared depth level, if specified (flat = none, subtle = light, layered = glows).
+6. **Avoidance rules** — if design.md has a section listing things to avoid (commonly "What NOT to Do", "Don'ts", "Anti-patterns", or "Do's and Don'ts"), verify none are present.
+
+Report violations as a checklist. Fix each one before serving.
+
+If no `design.md` exists (house-style-only path), verify:
+
+1. **Palette consistency** — the same bg, fg, and accent colors are used across all scenes. No per-scene color invention.
+2. **No lazy defaults** — check the composition against house-style.md's "Lazy Defaults to Question" list. If any appear, they must be a deliberate choice for the content, not a default.
