description	The marketing website, capsem.org. Use when editing copy, adding sections, or changing the site theme.

Marketing Website

The marketing site (capsem.org) is a single-page landing built with Astro 6 + Svelte 5 + Tailwind v4. Source lives in site/.

Dev workflow

cd site && pnpm run dev     # localhost:4321
cd site && pnpm run build   # Production build
cd site && pnpm run preview # Preview production build

CI and deploy rail

ci.yaml runs the merge-blocking site-build job under pr-gate. site.yaml deploys only on every push to main and smokes https://capsem.org/. This deploy rail is independent from binary releases, manual VM asset releases, and the release.capsem.org asset-channel workflow.

Architecture

Single page (site/src/pages/index.astro) composed of Svelte components. All marketing copy is centralized in site/src/lib/data.ts -- edit that file to change text, not the components.

Theme

Defined in site/src/styles/global.css using Tailwind v4 @theme tokens:

• Accent: --color-accent (blue), --color-accent-secondary (purple), gradient between them
• Surfaces: light (--color-surface) and dark (--color-surface-dark) variants
• Text: separate light-bg and dark-bg tokens, all WCAG AA compliant
• Buttons: 4 pill variants as @utility classes: btn-primary (gradient), btn-dark, btn-outline, btn-outline-dark
• Font: Inter (loaded from Google Fonts in Base.astro)

Component patterns

• Sections alternate light/dark backgrounds using section-dark utility class
• Section.svelte and SectionHeader.svelte provide consistent spacing and headings
• Interactive components use Svelte hydration directives: client:load (Nav) or client:visible (FAQ, CTA)
• gradient-text utility for accent-colored headings

Graphics and icons

Icons use inline SVG paths from site/src/lib/icons.ts, rendered via Icon.svelte. Favicons in site/public/ are generated from graphics/icon/1024w/capsem-logo-color.png.
