A validated EU business buyer (Österreich, the one cross-border option
this checkout offers) gets the sale zero-rated per §4 Nr. 1b UStG —
but only after a live VIES lookup confirms the VAT ID is actually
registered right now, never from format-validity alone (real
compliance risk otherwise). VIES unreachable fails closed: normal VAT
applies, no guessed exemption.
- lib/vies.ts: calls the EU's public VIES REST API.
- lib/vatExemption.ts: de-grosses item/shipping prices and computes
the exempt totals; also picks the actual destination country
(shipping override when set, billing otherwise).
- api/checkout/validate-vat: on-blur live check for instant feedback;
api/checkout/route.ts re-runs the same check server-side at submit
as the actual source of truth, and re-prices every line net-of-VAT
when exempt.
- CheckoutContent.tsx: VIES status + a live exempt-totals preview;
BestellbestaetigungContent.tsx mirrors it from the persisted
snapshot. Both blur-validate every other checkout field now too
(immediate inline errors, not just on submit).
- vatExempt/vatIdValidatedAt threaded through orderServer.ts,
customerAuth.ts, orderEmail.ts, and both invoice-download routes so
the invoice PDF and its e-invoice XML (companion payload-repo
commit) reflect the exemption correctly wherever it's rendered.

B2B checkout fields, split out from the e-invoicing migration and
picked back up now that it's shipped. Both fields are independently
optional, format-validated (shared regex in lib/vatId.ts, mirrored
server-side in api/checkout and api/account/profile), persisted in
the checkout draft, and saved as a customer profile default that
pre-fills future checkouts. Order/customer snapshot fields land in a
companion Payload backend commit.

- Round subtotal/discountAmount/total to 2 decimals before persisting an
order — float arithmetic on money was drifting into values like
84.30000000000001, invisible wherever a display already ran it through
toFixed(2), but stored as-is and visible raw in the Payload admin's
plain number field
- Low-stock hint now uses gap-1 consistently (was gap-2) in both
AddToCartButton/AddToCartInlineButton, for smaller/consistent spacing
above it regardless of context
- ProductSpotlight's CTA row now uses items-start at sm: — without it,
default cross-axis stretch made "Mehr erfahren" grow to match
AddToCartButton's height whenever the low-stock hint made that one
taller, so the link visibly looked "fatter" than the actual button

Bug fixes:
- Navbar login/logout state now updates immediately (custom ep-auth-changed
event) instead of requiring a hard reload
- Status-change email links were broken by an un-encoded "#" in the order
number; fixed for all 4 status emails
- Cart discount code: manual input field restored (was removed entirely)
- Quote-label underline now scales with the label's actual text width
- Number Ranges admin list now shows the invoice prefix/counter columns
Pricing & VAT:
- Prices show the real per-product VAT rate ("inkl. X% MwSt.") instead of
a generic disclosure
- Cart/checkout/confirmation totals show the actual € amount of VAT
included, broken down per rate when a cart spans more than one
(new lib/taxBreakdown.ts, shared with the invoice PDF's own math)
- Account order pages gained product thumbnails and the same VAT breakdown
Low-stock warning: a "Nur noch wenige verfügbar" badge/hint across the
shop grid, spotlight, and add-to-cart variant pickers, driven by the
existing lowStockThreshold field (still never exposes raw stock counts).
Invoice PDFs: product thumbnails on every line item, a plain "Netto"
label (rate was redundant, already stated on the MwSt. line below), no
more duplicate USt-IdNr. in the header, and — for a Stornorechnung
specifically — an explicit "Versand" line that was previously only
folded silently into the tax totals.
Checkout:
- Optional deviating shipping address (separate from the billing address
used for the invoice), with its own toggle + address form
- Full checkout draft persistence (name/address/shipping/payment
selections) survives navigating away and back, via localStorage
- Invoice PDF shows a third "Lieferadresse" block when the shipping
address differs from billing
Mobile navigation: fullscreen panel with a circular reveal animation from
the hamburger's corner, replacing the old in-flow accordion drawer; no
login CTA inside it (redundant with the always-visible header icon).
Admin-facing (Payload backend, mirrored where the frontend has a ported
copy of the same renderer): dashboard rebuilt as individual cards, split
into 3 task queues (received/processing/returns) instead of 2, revenue
and order counts now exclude cancelled/returned orders immediately, and
the low-stock alert links to the specific affected product(s) instead of
the unfiltered list. A new immediate email notifies the shop owner the
moment an order comes in, instead of only via the daily digest.
Testimonials admin list now groups by page instead of interleaving all
three grids' entries. ~45 English admin field descriptions translated to
German for consistency.

- ProductGrid/AddToCartInlineButton/AddToCartButton now show "Ausverkauft"
and disable add-to-cart per variant (or product-level with no variants),
derived from trackInventory/stock/allowBackorder via isOutOfStock().
- AddToCartButton (todo-cards Hero+Pricing, homepage spotlight) gains the
same variant <select> AddToCartInlineButton already had — all three call
sites already fetch full product data server-side.
- /api/checkout re-validates stock server-side (depth-in-defense, not just
the disabled button), rejecting when trackInventory is on, allowBackorder
is off, and requested qty exceeds stock.

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.

No test infrastructure existed in this repo yet. Covers the pure logic
most likely to silently produce wrong numbers on a live order: discount/
shipping math, per-rate invoice grouping, and bundle-contents string
building. Extracted describeBundleContents() out of the checkout route
into its own module so it's importable from a test (route.ts files only
allow HTTP-method exports).
Customers can now select which items and how many units to return
instead of only the whole order. The Gutschrift reflects only the
returned quantities, excludes shipping (already delivered), and leaves
the original discount untouched — confirmed policy, not an engineering
default. Stornorechnung (pre-shipping cancellation) is unaffected and
stays a full reversal including shipping.
Company data now has its own Payload admin group and a live in-browser
PDF preview (react-pdf's PDFViewer) instead of just a plain settings
form. Invoice header is a brand-colored rule instead of a filled band,
and the footer is now pinned to the page bottom instead of following
content flow.
Invoice + Stornorechnung/Gutschrift PDFs get a modern header-band layout,
a "bereits beglichen" badge for immediately-paid orders, labelled bank
details, and a per-tax-rate summary breakdown. Correction invoices can
now be re-downloaded from the account (regenerated deterministically,
not stored as files, same approach as the original invoice). Return
requests capture a reason. Products can define bundles (bundleItems) and
a per-product VAT rate override, both snapshotted onto order items.
Invoice PDFs (§14 UStG line items, tenant-configurable VAT rate) are now
generated at checkout and attached to the confirmation email, plus
available on demand from the order-detail page. Payload-side, orders now
also email the customer on shipped/cancelled/return_requested/returned,
with Stornorechnung/Gutschrift correction PDFs attached for the latter two
so the original invoice's immutable number stays honest.
The always-visible "Schon Kundin?" toggle was gendered and shown to every
logged-out visitor regardless of relevance. Card 1's email field now
checks on blur (/api/account/check-email) whether that address already
has an account, and only then swaps in a gender-neutral login form,
pre-filled — the collision check in handleSubmit stays as a fallback.
The order-confirmation and password-reset emails also got a real visual
pass: same warm background/brand color/circular success-icon treatment as
the on-screen /bestellbestaetigung page, serif heading, thin brand
divider, table-based layout for email-client compatibility. Copy is
on-brand and a little playful now instead of generic transactional
boilerplate.

Password reset uses Payload's built-in forgot/reset-password flow,
customized to link to this app instead of the Payload admin. Order
confirmation email and the password-reset email's wording both come from
a new Payload email-templates collection, editable without a deploy and
previewable via Live Preview at /email-preview/[type] (same mechanism as
Posts/LegalPages/Testimonials, sample data instead of a real document).
Also: order numbers get a random suffix (prevents guessing, motivated by
a considered-and-deferred guest order-lookup feature); the discount code
field only shows in the cart when a code is actually active (codes now
apply via a ?code= link instead of manual entry); and three navigation
gaps found while testing — no reachable login link with an empty cart, no
logout link anywhere, no way back from profile to order history.

request.url reflects the container's internal 0.0.0.0:3000 behind
Caddy's reverse proxy, not the public domain — sent real browsers to an
unreachable address. Caught live during post-deploy verification.

Complements Payload's per-account login lockout with per-IP rate limiting
on auth routes; proxy.ts silently refreshes an active customer's session
via Payload's built-in refresh-token endpoint instead of a long-lived
token. Registration now sends a non-blocking email-verification link
(doesn't gate login, since checkout registers and immediately logs in
mid-purchase). /konto/profil gets GDPR export/delete; order detail pages
get self-service cancel/return-request, backed by a Payload hook that
closes a real gap (a customer's JWT could previously PATCH any field of
their own order, not just status). Checkout failures now email an alert
independent of Payload's own health, since Kuma's uptime checks can't see
an order silently failing to persist.

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.

Discount codes:
- New shared lib/cartTotals.ts (computeSubtotal/computeCartTotals) factored
out of the previously-triplicated subtotal/totalSavings/total math in
CartContent/CheckoutContent/BestellbestaetigungContent, extended to also
fold in a discount amount (percent or fixed, clamped so total can't go
negative).
- lib/discount.ts mirrors lib/cart.ts's exact localStorage pattern so an
applied code survives the /cart -> /checkout transition without a second
input field — Checkout only displays it.
- New /api/discount/validate (read-only check) and /api/discount/redeem
(re-validates + increments the redemption counter, called once from
checkout's handlePurchase right before the OrderSnapshot is written).
Both talk to Payload's new discount-codes collection through
lib/discountServer.ts, a server-only module kept separate from
lib/payload.ts on purpose (that file is also imported by "use client"
components; the RSC-boundary break hit earlier this session was exactly
this mistake with next/headers).
- OrderSnapshot gains discountCode/discountAmount so /bestellbestaetigung
displays what was actually applied instead of losing it on recompute.
RelatedProducts: no longer falls back to re-suggesting a product already
in the cart just to pad the grid out to 3 cards — shows only the
genuinely available remainder (down to 1 card), centered in the 12-column
grid instead of left-aligned.
Testimonials on /todo-cards, /newsletter, /challenge now come from the new
Payload testimonials collection via a shared TestimonialsGrid component,
instead of 3 separately hardcoded arrays.
Adds Next.js Draft Mode (/api/preview) plus Live-Preview-aware client
wrappers (LiveRichText, LiveTestimonialsGrid, LivePostContent) for posts,
legal pages, and testimonials — mounted only while Draft Mode is enabled,
so ordinary visitors keep getting the plain static components.
Products now come from Payload's new "products" collection instead of a
hardcoded catalog, same pattern already used for blog posts:
- lib/payload.ts: getProducts()/getProductBySlug() (server-side fetch,
60s ISR)
- New /api/products route so client components (CartContent,
RelatedProducts) can reach the same data without a server-only import
- lib/products.ts: useProducts() hook replacing the old PRODUCTS record
- ProductGrid (/shop) fetches server-side directly; now shows all
catalog products except notizbuch-klarheit (matches Figma's 4-card
page-shop-overview — still cross-sold via RelatedProducts)
- ProductSpotlight and /todo-cards' Pricing now pull price/photo from
the same CMS product instead of a separately hardcoded "12,90 €", so
the two can't silently drift apart
- formatPrice moved to a new lib/format.ts (plain, no "use client") —
Server Components can't call functions exported from a "use client"
module directly, which lib/products.ts now is because of the hook
Also fixes two unrelated bugs surfaced along the way: the add-to-cart
button visibly resizing when its "Hinzugefügt ✓" success state showed
(fixed with a CSS-grid text stack sized to the wider of the two
strings), and removes the now-unused local product images from public/.
