* feat: comprehensive UI design audit and normalization

Dashboard audit:
- Fix muted-foreground contrast (4.31:1 → 5.08:1) for WCAG AA
- Add prefers-reduced-motion media query for all animations
- Replace border-l-2 accent anti-pattern with subtle full-border colors
- Add aria-expanded to toggle buttons, role="status" to live counters
- Fix touch targets on deadline buttons (28px → 36px)
- Vary section spacing for rhythm (mb-12/mb-10/mb-8)
- Remove unused imports and dead code

Transactions audit + hardening:
- Add pagination (200 per page) with "Ladda fler" button
- Replace height animation with transform-only exit animation
- Show batch progress in floating action bar during processing
- Fix batch bar mobile overlap (bottom-20 on mobile)
- Replace clickable badges with proper button elements
- Add safe area padding to fullscreen swipe view
- Add response.ok check to suggestion fetch
- Add truncation to invoice number buttons

Invoicing audit:
- Remove border-l-4 accent pattern from invoice cards
- Replace string concatenation with cn() utility

Systemic sweep (34 files):
- All page headings: font-bold → font-display font-medium (Fraunces)
- All stat numbers: font-bold → font-display font-medium tabular-nums
- All hard-coded blue/amber/emerald colors → design tokens
- Remove all dark mode overrides (tokens handle automatically)
- Tint pure white card background to 99%

Design context added to CLAUDE.md with brand personality,
aesthetic direction, and 5 design principles.

- Add confirmation dialog for account deletion (ChartOfAccountsManager)
- Remove console.error from production code (JournalEntryList, JournalEntryForm)
- Fix contradictory h-7/min-h-[44px] button sizing → h-10 (ChartOfAccountsManager)
- Increase BAS catalog "Lägg till" touch target h-7 → h-9
- Improve loading state with spinner (JournalEntryList)

- Add response.ok check on journal entry fetch
- Add aria-expanded to entry expand buttons
- Add tabular-nums to desktop debit/credit columns

* fix: onboarding and empty state improvements

Onboarding:
- Replace font-serif with font-display (Fraunces) for brand consistency
- Remove console.error calls from production code

Empty states:
- Fix broken /transactions/new link in EmptyTransactions (route doesn't exist)
- Add actionHref fallback to EmptyCustomers when no onAction prop provided
- Improve EmptyTransactions description copy

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: clarify Swedish UX copy — terminology, errors, descriptions

Terminology consistency:
- "Försenad" → "Förfallen" for overdue invoices (customers/[id])
- "bokföringsorder" → actionable description in bookkeeping page
- "verifikation har bifogats" → "underlag har bifogats" in doc warning
- "Fortsätt ändå" → "Bokför utan underlag" (specific action)

Error messages — replace generic "Fel" + "Något gick fel" with specific:
- "Något gick fel vid bokföring" → "Transaktionen kunde inte bokföras"
- "Något gick fel vid matchning" → "Transaktionen kunde inte matchas"
- "Kunde inte hämta X" → "Kunde inte ladda X" + recovery hint
- Add "Försök igen" guidance to all error toasts

Page descriptions — replace redundant with actionable:
- Invoices: "Skapa och hantera" → "Skicka, följ betalningar, skapa kreditnotor"
- Bookkeeping: list of features → actionable description

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: design critique — dashboard affordance, reports description

Dashboard:
- Add ChevronRight indicator to clickable summary cards
  (Att få betalt, Koppla bank) to distinguish from static cards
- Add cursor-pointer to linked cards

Reports:
- Replace feature list description with actionable guidance
  "Huvudbok, grundbok..." → "Generera skattedeklarationer..."

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: replace generic "Fel" error toasts with specific messages

Deadlines: 5 generic "Fel" → specific per-action titles
  (create, toggle, edit, delete, load)
Expenses detail: 5 generic "Fel" → specific per-action titles
  (load, approve, pay, credit, delete)
Expenses new: 3 generic "Fel" → instructional validation messages
  (supplier name, supplier selection, invoice number)
Customers: 1 generic "Fel" → specific load error with recovery hint

All error toasts now follow pattern:
  title = what failed, description = how to recover

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: replace all remaining generic "Fel" error toasts (37 instances)

Systematic sweep across 12 dashboard pages replacing generic
title: 'Fel' with context-specific error titles:

- Load errors: "Kunde inte ladda [resurs]"
- Action errors: "[Åtgärd] misslyckades"
- Validation: "[Fält] saknas"

Every error toast now tells the user what failed without needing
to read the description. Recovery hints added where missing.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: import flow — normalize stat typography, remove console.warn

- Replace font-bold with font-display font-medium on 13 stat numbers
  across SIEPreviewStep, BankFilePreviewStep, BankFileConfirmStep,
  ImportResultStep (missed by systemic sweep since these are in
  components/import/, not app/(dashboard)/)
- Add tabular-nums to stat numbers displaying counts/currency
- Remove console.warn in ArcimMigrationWorkspace

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: final cleanup — console statements, remaining font-bold stats

Remove production console statements:
- Step1EntityType: remove debug console.warn (dead code after onNext)
- TransactionBookingDialog: remove console.error on doc link failure
- JournalEntryAttachments: remove 3 console.error calls

Normalize remaining font-bold stat displays:
- SwipeCategorizationView: 3 instances (completion, amount displays)
- NEDeclarationView: yearly result heading + value

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: address Greptile review feedback

loadMoreTransactions: add inbox item enrichment matching fetchTransactions
- Paginated transactions now fetch invoice_inbox_items in parallel
- Fixes missing document indicator, template suggestions, and inbox
  match card for transactions loaded via "Ladda fler"

fetchAllPages: add maxPages guard (default 500) to prevent infinite loop
- If Arcim gateway returns hasMore:true indefinitely, the loop now
  exits after 500 pages instead of running forever
