Scaffolding Marketing Sections

Purpose

Translate Information Architecture section definitions into Svelte 5 component scaffolds. Each IA section has an archetype, layout pattern, and content slots -- this skill maps those to concrete markup, props, and design token usage.

Source Documents

Read these before scaffolding any section:

• IA: /workspace/docs/marketing/information-architecture.md -- section definitions, archetypes, layout patterns, content slots
• Wireframe Copy: /workspace/docs/marketing/wireframe-copy.md -- exact copy for every content slot
• Brand Packet: /workspace/docs/marketing/brand-packet.md -- voice, color tokens, typography, spacing
• Design Tokens: /workspace/apps/marketing-site/src/app.css -- @theme block, component classes, animation classes
• Design Rule: /workspace/.claude/rules/design-system.md -- enforcement guardrails

Existing Components (Reference Implementations)

Study these before writing new sections -- they demonstrate the project's patterns:

Component File Pattern

<script lang="ts">
  // 1. Imports (Svelte lifecycle, GSAP if animated, child components)
  import { onMount } from 'svelte';

  // 2. Props (if the section takes external data)
  // Most sections are self-contained with hardcoded IA copy

  // 3. State (if interactive)
  let sectionRef: HTMLElement;
</script>

<!-- Section with semantic ID for anchor navigation -->
<section
  id="section-anchor-id"
  bind:this={sectionRef}
  class="py-24 px-6 lg:px-16"
  aria-labelledby="section-heading-id"
>
  <div class="mx-auto max-w-[1200px]">
    <!-- Section header -->
    <div class="text-center mb-12">
      <h2
        id="section-heading-id"
        class="text-display font-bold tracking-tight text-text-primary mb-4"
      >
        {/* IA section-headline slot */}
      </h2>
      <p class="text-body-large text-text-secondary max-w-2xl mx-auto">
        {/* IA section-subheadline slot */}
      </p>
    </div>

    <!-- Section body (archetype-specific layout) -->
    <!-- ... -->
  </div>
</section>

File naming: SectionName.svelte in PascalCase. Place in apps/marketing-site/src/lib/components/.

Examples: CategoryStake.svelte, CredibilityBar.svelte, MechanismSection.svelte, ValueGrid.svelte, ProofBlock.svelte, CommunityBlock.svelte, CtaBlock.svelte.

Props Interface Pattern

Most marketing sections are self-contained (copy comes from wireframe, not props). Use $props() only when a component needs external data:

<script lang="ts">
  // Props for reusable sub-components
  interface Props {
    title: string;
    description: string;
    icon?: string;
  }

  let { title, description, icon }: Props = $props();
</script>

For top-level sections, hardcode the IA copy directly -- this makes the component a self-documenting artifact that matches the IA exactly.

Trust Mechanic Integration

Each IA section specifies a trust mechanic. Integrate them as follows:

Section	Trust Mechanic	Implementation
1: Hero	Integration logos	Logo pills row below terminal: "Works with Claude Code, Codex, OpenCode"
2: Social Proof Bar	Metric + logos + badge	Metric-value/label pairs + logo pills + badge pills
3: Mechanism	Architecture proof	The code blocks themselves are the proof -- show real YAML and CLI output
4: Value Grid	Per-card micro-proof	Inline code references within card descriptions (e.g., musher bundle apply)
5: Proof Block	Founder credential + metrics	Credential paragraph + metric-showcase grid
6: Community	GitHub + Discord links	Link buttons (inspect the repo yourself)
7: CTA	Friction reducers	Badge pills below install command

Responsive Patterns

Every section must work at 375px, 768px, and 1280px:

• Grid columns: grid-cols-1 md:grid-cols-2 lg:grid-cols-3 (or lg:grid-cols-12 for hero)
• Side padding: px-6 md:px-10 lg:px-16
• Section padding: py-24 standard, py-32 for CTA block
• Text alignment: text-center lg:text-left for hero; text-center for all others
• Stacking: Grid items stack to single column on mobile

Anti-Patterns

DO NOT	DO
Create custom card styles	Use .card, .glass, .bento-item from app.css
Use className	Use class (this is Svelte, not React)
Use on:click	Use onclick (Svelte 5 event syntax)
Use export let for props	Use let { prop } = $props()
Use $: for reactivity	Use $state(), $derived(), $effect()
Add arbitrary spacing (p-[37px])	Use the spacing scale from @theme
Use raw hex colors	Use design token classes (bg-surface-02, text-text-primary)
Use Tailwind default palette	Use project tokens (bg-signal-action, not bg-blue-500)
Create separate CSS file	Use Tailwind utilities or app.css component classes
Import from React/Vue	This is SvelteKit 2.x + Svelte 5

Workflow

1. Read the IA section definition -- archetype, layout pattern, content slots, trust mechanic
2. Read the wireframe copy -- exact text for every content slot
3. Check existing components -- does a component already cover this archetype?
4. Scaffold the component using the archetype-to-component mapping above
5. Fill content slots using the slot-to-markup translation table
6. Add trust mechanic per the integration table
7. Add anchor id for in-page navigation (e.g., id="mechanism")
8. Add aria-labelledby pointing to the section heading
9. Test responsive at 375px, 768px, 1280px widths (mentally or via dev tools)
