docs(design): add two-accent system, selective mono, and dark mode decisions

Decisions from plan-design-review and plan-eng-review:
- Two-accent system: amber = state (nav, pills), blue = action (buttons)
- JetBrains Mono selective: codes/numbers only, text uses DM Sans
- Dark mode now in scope for Commit 0.5
- Add TODOS.md with deferred P2 items

-### Approach: Restrained with warm accent
+### Approach: Two-accent system (amber state + blue action)
 Every admin tool is blue. This one uses amber — reads as "operational" and "attention-worthy."
+- **Amber (--accent):** Navigation active state, filter pill active, accent backgrounds. "Where you are."
+- **Blue (--info):** Primary buttons, CTAs, actionable links. "What you can do."
+- Primary buttons (`btn-primary`) stay blue for clear action hierarchy.
 
 ### Light Mode (default)

+# TODOS

+## P2: Refactor sync_service.py in module separate
+**What:** Split sync_service.py (870 linii) in: download_service, parse_service, sync_orchestrator.
+**Why:** Faciliteza debugging si testare. Un bug in price sync nu ar trebui sa afecteze import flow.
+**Effort:** M (human: ~1 sapt / CC: ~1-2h)
+**Context:** Dupa implementarea planului Command Center (retry_service deja extras). sync_service face download + parse + validate + import + price sync + invoice check — prea multe responsabilitati.
+**Depends on:** Finalizarea planului Command Center.
+
+## P2: Email/webhook alert pe sync esuat
+**What:** Cand sync-ul gaseste >5 erori sau esueaza complet, trimite un email/webhook.
+**Why:** Post-lansare, cand app-ul ruleaza automat, nimeni nu sta sa verifice constant.
+**Effort:** M (human: ~1 sapt / CC: ~1h)
+**Context:** Depinde de infrastructura email/webhook disponibila la client. Implementare: SMTP simplu sau webhook URL configurabil in Settings.
+**Depends on:** Lansare in productie + infrastructura email la client.
