Completes the frontend half of the Payload backend's variant/inventory/
tracking work (see that repo's own commit):
- **Cart**: CartItem gained an optional `variant?: string` field — every
function that used to match a line by `id` alone (addToCart/
removeFromCart/setQuantity) now matches by `(id, variant)` together via
a shared sameLine() helper, so two lines for the same product with
different variants stay separate entries. `variant` undefined on both
sides (the no-variants case) still matches by simple equality, so every
pre-existing call site keeps working unchanged.
- **Selection UI**: AddToCartInlineButton renders a <select> above the
button when given a non-empty `variants` prop (ProductGrid/
RelatedProducts pass product.variants straight through); defaults to
the first variant.
- **Pricing**: cartTotals.ts's new effectivePrice(entry, product) — a
variant's priceOverride wins over the base product price. Every cart/
checkout/order-confirmation total and per-line price display now goes
through this instead of reading product.price directly (fixes both a
wrong-price bug and a duplicate-React-key bug the old `key={product.id}`
pattern would have had the moment two variants of one product were both
in the cart).
- **Checkout**: re-validates the requested variant server-side (same
"never trust the client" reasoning as price re-derivation) — a variant
name that doesn't exist on that product fails the whole checkout.
variantName snapshots onto orders.items, shown as a parenthetical next
to the product name on the confirmation email, both invoice PDF types,
and the order-detail page.
- **Cross-device cart**: Customers.cart[].variantName (synced via
/api/account/cart) carries the selection through a login/logout cycle,
not just the current session.
Also adds tracking-number display: /konto/bestellungen/[orderNumber]
shows a clickable link when orders.trackingNumber is set, built by a new
app/lib/tracking.ts that mirrors the Payload backend's own copy
byte-for-byte close (same carrier set/URL patterns) so what a customer
sees here matches exactly what the order-shipped email already links to.

Checkout now persists orders server-side (Payload orders collection,
re-priced from live product data, discount codes redeemed exactly once)
instead of writing a client-only sessionStorage snapshot. Buying requires
an account (registration inline in checkout, no separate step) — accounts
get order history with delivery status, profile/address editing, password
change, and a cart that syncs across devices while logged in.

Matches the Figma mockup (checkmark hero, order summary card,
delivery-status panel, testimonial band) with the checkout's 4-step
bar inserted (all steps done) and the "Bis dahin: Lass dich
inspirieren" block omitted, per request.
Extracted the step bar into a shared CheckoutSteps component so
/checkout and /bestellbestaetigung don't duplicate it. The actually-
selected shipping cost and payment method are captured into a
sessionStorage snapshot by /checkout's "Jetzt kaufen" click (there's
no real order backend, so this click is what "placing the order"
means here) and read back on the confirmation page — not just
defaulted to the first active method of each, so the receipt matches
what the shopper actually picked. Also tightened the checkout
newsletter-consent copy ("Wenn du zustimmst" instead of "Wenn du
oben zustimmst").
- New /shop overview, /cart (real cart state via useSyncExternalStore),
/versand (shipping policy page with TOC) and /newsletter detail page
- Cart: quantity/removal, order summary, related-products cross-sell
with randomized picks, VersandModal quick-reference instead of
navigating away, MwSt. disclosure next to unit prices
- Add-to-cart UX: inline success feedback (green state) plus a
fly-to-navbar-cart-icon animation (CartFlyProvider) with a delayed
badge count-up; AddToCartButton no longer navigates straight to /cart
- Shared lib/products.ts catalog and lib/shipping.ts constants (cost,
free-shipping threshold, handling/transit days) so cart, trust badges
and the versand page can never drift apart
- Fix Navbar smooth-scroll easing (ease-out instead of ease-in-out, no
more perceived start delay); compress newsletter modal photo
2.4MB -> 85KB to fix first-open jank
New /todo-cards page (Hero, How-it-works, Focus, Testimonials, Pricing)
built with the fluid clamp() token system (app/lib/fluid.ts) and
scroll-reveal animations (app/components/Reveal.tsx), matching styling
consistency with /challenge's testimonial section.
Navbar: page-aware active state and anchor-link navigation from any
route (not just "/"), fixed logo click to actually navigate instead of
silently rewriting the URL, fluid nav text size, custom hash-scroll
handling for cross-page anchor links.
Hero: responsive breakpoint fix for the text/image split at Tablet
widths, entrance animation for the brand's orange dot, removed a red
dot artifact from hero.png.
Also includes prior uncommitted work on About/Blog/Newsletter/Footer
and the cart lib (app/lib/cart.ts).
