Subject: [PATCH] =?UTF-8?q?feat(web):=20=5Fapp=20shell=20+=20dashboard=20+?=
 =?UTF-8?q?=20factures=20liste=20&=20d=C3=A9tail?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Layout shell pour l'app authentifiée :
- routes/_app.tsx : pathless layout avec auth-guard + onboarding-guard
  (signature null → redirect onboarding/compte)
- AppLayout : grid sidebar + topbar + main + tab bar mobile
- AppSidebar (lg+) : nav verticale + mini compteur rubis en bas
- MobileTabBar : 4 onglets fixed bottom (Accueil, Factures, Plans, Réglages)
- AppTopbar : sticky bg-cream/85 + backdrop-blur, greeting + date sur desktop,
  brand sur mobile
- UserMenu : Radix Popover, avatar initiales rubis, logout mutation

Dashboard / (cf. wireframe 4.1) :
- RubisHero : ◆ 56px + drop-shadow rubis-tinted, "X rubis gagnés" en italic
  rubis sur "gagnés", verbalisation conversion en heures, progression mensuelle
- 4 KpiCard scannables : À relancer, En cours, Encaissé, DSO
  (delta en rubis-deep si intent positif, jamais de vert succès)
- ActivityFeed : journal du jour avec icônes Lucide tonalisées
- TopLatePayers : "Retards récurrents" (pas "mauvais payeurs", cf. marque)
- Quick actions mobile (+ Photo de facture / + Saisir)

Factures liste /factures (wireframe 2.4 + 2.1) :
- 3 états : 0 facture → dropzone full-page · filtre vide → mini-empty
  · populated → filter chips + table desktop / cards mobile
- FilterChips : sync URL (validateSearch zod), counts entre parenthèses
- InvoiceTable : ligne entière cliquable (onClick + role=link + onKeyDown),
  chevron Link séparé pour right-click "ouvrir nouvel onglet"
- InvoiceCardList : version mobile aérée
- StatusBadge : 6 statuts mappés palette marque (rubis solide pour "À valider",
  ink pour "En relance", crème+✓ pour "Encaissée")
- Skeleton pulsé pendant le fetch

Détail facture /factures/$id (wireframe 4.2) :
- Header : eyebrow client + numéro + montant + échéance + délai (J−4 rouge)
  + StatusBadge inline
- Actions : Marquer encaissée (mutation + bonus rubis + invalidate)
- Layout 2-col : Timeline (1.4fr) + sidepanel client/notes (1fr)
- Timeline primitive : pastilles passé/présent/futur (rubis-glow ✓ /
  rubis solide + Clock + ring glow / cercle vide)

Bug fix routing :
- factures.$id.tsx était nesté sous factures.tsx (flat naming TanStack Router)
  → la liste s'affichait à la place de la détail. Renommé factures_.$id.tsx
  pour escape le layout parent. URL inchangée (/factures/$id).

Placeholders soignés : /plans, /clients, /parametres avec EmptyState draft
(bordure pointillée + message qui assume "ça arrive").

MSW étendu :
- mocks/seed.ts : 5 clients, 4 plans avec étapes complètes (Standard B2B,
  Rapide, Patient, Ferme), 10 invoices avec statuses variés calibrés
  sur le wireframe
- handlers/dashboard.ts : GET /dashboard/{kpis,activity,top-late}
- handlers/invoices.ts : GET /invoices (filtres + tri par priorité statut),
  GET /invoices/counts, GET /invoices/:id (timeline calculée depuis le plan),
  POST /invoices/:id/mark-paid (passe en paid + bonus rubis)

Lib étendue :
- format : formatDueDelta (J+10, J−4 avec − typographique), isOverdue
- routes/index.tsx supprimé (remplacé par _app/index.tsx)

Bundle prod : 117 KB gzip core, chaque route en chunk dédié (dashboard
inline dans _app, factures 3.69 KB gzip, factures._id 2.22 KB gzip).
