NodeBranchRenderer draws a single NodeBranch inside the ImGui / ImNodes graph canvas. The node is divided into four visual sections separated by horizontal dividers, matching the validated mockup:

┌─────────────────────────────────────────────────┐
│  Section 1 — Title bar (blue background)        │
│    Is Health Critical?                          │
├─────────────────────────────────────────────────┤
│  Section 2 — Exec pins (static, never editable) │
│    >> In                         Then >>        │
│                                  Else >>        │
├─────────────────────────────────────────────────┤
│  Section 3 — Conditions preview (READ-ONLY)     │
│      [mHealth] <= [2]       (green, monospace)  │
│  And [mSpeed] <= [100.00]                       │
│  Or  [mSpeed] == [Pin : 1]                      │
├─────────────────────────────────────────────────┤
│  Section 4 — Dynamic data pins (yellow, cond.)  │
│  * In #1: [mSpeed] == [Pin : 1]                │
└─────────────────────────────────────────────────┘

Interaction:

• Hover over a condition row -> tooltip showing preset details.
• Click a condition row -> fires OnConditionClicked(conditionIndex).
• Dynamic pins support drag/connect via ImNodes.
• Section 4 is only rendered when at least one dynamic pin exists.

Auto-update: Call NotifyPresetChanged(presetID) whenever a preset is updated so that the cached preview strings are refreshed.

C++14 compliant — no std::optional, structured bindings, std::filesystem.
