Z User e45b68bb8b feat: IMAP mail sync with thread-to-contact matching (PRD §6.1)
Real IMAP connection via imapflow library:
- Connects to IMAP server (IMAPFlow, TLS on port 993)
- Fetches recent messages (configurable limit, default 20)
- Extracts: from, fromEmail, subject, date, snippet (200 chars)
- Thread-to-contact matching (PRD §6.1):
  1. Match sender email against persons table
  2. If no person match, extract domain and match against company.website
  3. Returns matchedCompany + matchedPerson for each email
- Audit-logged (action: crm.mailsync:imap)
- Zod validated (host, port, user, password, folder, limit)
- 502 on IMAP connection failure with detail
- 400 on validation failure

Tested: invalid creds → 502 'IMAP connection failed', missing host → 400

Trading Terminal Design System

Category: Themed & Unique Bloomberg-style financial trading terminal. Dark-only, data-dense, cyan/coral buy/sell signals. Everything readable at a glance from two meters away.

1. Visual Theme & Atmosphere

A professional-grade financial data terminal. Dense, information-rich layouts designed for traders who need to monitor multiple markets simultaneously. Dark surfaces reduce eye strain during long sessions. Cyan accent (#00D4AA) signals positive/buy, coral (#FF4757) signals negative/sell. Everything readable at a glance from two meters away.

  • Visual style: dense, data-first, professional
  • Color stance: dark surfaces with high-contrast data colors
  • Design intent: keep outputs recognizable to this style family while preserving usability and readability

Prior Art

Bloomberg Terminal, Refinitiv Eikon, FactSet, TradingView Pro. All share: dark-only surfaces, monospace data fonts, tabular layouts with no decorative spacing, and color-coded buy/sell signals.

.order-book-row {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
  padding: var(--space-1) 0;
  border-bottom: 1px solid var(--color-border);
}

.price-card {
  background: var(--color-surface);
  border: 1px solid var(--color-border);
  padding: var(--space-4);
  display: flex;
  flex-direction: column;
  gap: var(--space-2);
}

}
.price-card-change.positive { color: var(--color-gain); }

Ticker Bar

Horizontal scrolling single-line ticker for market overview.

.ticker-bar {

  gap: var(--space-6);
  overflow-x: auto;
  padding: var(--space-2) 0;

}

5. Layout Principles

Grid-based dense layout. Multiple data columns visible simultaneously. Panels share borders, not gaps. No rounded corners — sharp edges communicate precision. The layout is tabular: rows of data, columns of similar data.

6. Depth & Elevation

Trading terminals use flat design with border-based separation — no shadows. Surface shifts (#141414 vs #0D0D0D) convey elevation. Thin borders (#2A2A2A) define panel boundaries without decorative elements.

7. Do's and Don'ts

  • Do not use color alone to signal buy/sell — always pair with a directional icon or label
  • Do not animate data values decoratively — traders need instant, stable reads
  • Do not use rounded corners — sharp precision aesthetic only
  • Do not use light mode — trading terminals operate in dim environments
  • Do not show more than 5 price points in a column — cognitive overload reduces decision speed
  • Do not use gradients — flat fills only

8. Responsive Behavior

Terminal layouts target desktop-first (1280px+). On narrower viewports, columns collapse from rightmost to leftmost, prioritizing price and change data. Below 768px, single-column stack with horizontal scroll for overflow data. No breakpoints alter the dark-only constraint.

9. Agent Prompt Guide

When generating a trading terminal interface, prompt the model to:

  • Use JetBrains Mono for all numeric data; Inter for labels and headings
  • Always show gain/loss values in monospace with color coding (#00D4AA green, #FF4757 red)
  • No rounded corners on any element
  • Use 100ms transitions for price updates, 150ms for hover states
  • Never use light mode or bright backgrounds
  • Include a horizontal ticker bar with scrolling price updates
  • All data changes retain old value briefly before swapping to prevent flash blindness
