/**
 * Shared brand constants and Logo component for all PDF documents
 * (invoices, credit notes, future quotes / reminders).
 *
 * Phase 7 fix: previously each PDF generator carried its own copy
 * of BRAND and its own Logo. When Cedric customized the invoice
 * issuer block in his deployment (real Strasse Nr., PLZ, etc.),
 * the credit note PDF kept the original placeholders because it
 * had its own duplicate. Hoisting both here means every PDF reads
 * the same source of truth.
 *
 * To change the brand: edit BRAND below. To change the logo:
 * edit Logo below. To change the issuer info Cedric ships: edit
 * BRAND.issuer — both billing-pdf.tsx and credit-note-pdf.tsx pick
 * it up automatically.
 *
 * The Logo component accepts a `color` prop so the credit-note
 * variant can render the SAME shape tinted red (the document
 * family is visually consistent; only the accent colour signals
 * "this is a credit, not an invoice").
