Rebrand store as Pulse with athletic theme and shared typography

- Pulse theme tokens in app.schema.json: Archivo Black headings (weight 400)
  + Inter body, white bg / black pill buttons, xl radius, AI-generated
  athletic imagery
- Add headerFontWeight theme prop so single-weight fonts (Archivo Black)
  load and render correctly; ThemeProvider applies font-family + weight
  inline so Typography works regardless of `as` element
- New shared Heading component (tagline / title / subtitle with size +
  align + tone variants) and Typography caption variant for taglines;
  refactor features, faq, cta, testimonials, products-carousel,
  products-grid, collection-grid, recommended-products, image-gallery,
  newsletter-cta to use them
- Hero accepts a `buttons` array (label / href / variant) replacing
  primaryCta/secondaryCta; cover-image component removed and existing
  cover blocks migrated to Hero blocks with `buttons: []`
- Newsletter CTA uses shadcn Button + Input so it inherits theme radius;
  stacked layout fixed to keep the image
- Product/collection card titles use Typography subtitle variants
  (font-body), heading font weight is theme-controlled
- Remove orphan commerce/shop-header.tsx and commerce/shop-footer.tsx;
  the editor-driven navigation/footer are the live chrome
