Apply LotusGuild design system convergence (aesthetic_diff.md)

- §5: Section headers now ╠═══ TITLE ═══╣ (was ═══ TITLE ═══)
- §8+§18: Replace inline-style showTerminalNotification() with lt.toast.*
  delegate wrapper; load base.js from /base.js
- §12: Fix --text-muted #008822→#00bb33 (WCAG AA contrast)

base.js symlinked from web_template into public/ so lt.* is available.
showTerminalNotification() is kept as a thin wrapper so all existing
call sites continue to work unchanged.

 ## Overview
 
 PULSE is a centralized workflow execution system designed to orchestrate operations across distributed infrastructure. It provides a powerful web-based interface with a vintage CRT terminal aesthetic for defining, managing, and executing workflows that can span multiple servers, require human interaction, and perform complex automation tasks at scale.

 PULSE uses MariaDB with the following tables:
 
-- **users**: User accounts from Authelia SSO
-- **workers**: Worker node registry with metadata
-- **workflows**: Workflow definitions (JSON)
-- **executions**: Execution history with logs
+| Table | Purpose |
+|-------|---------|
+| `users` | User accounts synced from Authelia SSO |
+| `workers` | Worker node registry with connection metadata |
+| `workflows` | Workflow definitions stored as JSON |
+| `executions` | Execution history with logs, status, and timestamps |
 
-See [Claude.md](Claude.md) for complete schema details.
+### `executions` Table Key Columns

+| Column | Description |
+|--------|-------------|
+| `id` | Auto-increment primary key |
+| `worker_id` | Foreign key to workers |
+| `command` | The command that was executed |
+| `status` | `running`, `completed`, `failed` |
+| `output` | Command output / log (JSON or text) |
+| `created_at` | Execution start timestamp |
+| `completed_at` | Execution end timestamp |
+
+### `workers` Table Key Columns
+
+| Column | Description |
+|--------|-------------|
+| `id` | Auto-increment primary key |
+| `name` | Worker name (from `WORKER_NAME` env) |
+| `last_seen` | Last heartbeat timestamp |
