 - Character/Variable types (`Character`, `Variable`) and extracted node data types (`DialogueNodeData`, `VariableNodeData`) are in `src/types/flowchart.ts`
 - New JSONB fields (characters, variables) must be defaulted to `[]` when reading from DB in page.tsx to handle pre-existing data
 - Reusable `Combobox` component at `src/components/editor/Combobox.tsx` - use for all character/variable dropdowns. Props: items (ComboboxItem[]), value, onChange, placeholder, onAddNew
+- `ProjectSettingsModal` at `src/components/editor/ProjectSettingsModal.tsx` manages characters/variables. Receives state + callbacks from FlowchartEditor
+- Characters and variables state is managed in `FlowchartEditorInner` with `useState` hooks, passed down to the modal

+- What was implemented: Character management UI in the project settings modal
+- Files changed:
+  - `src/components/editor/ProjectSettingsModal.tsx` - New modal component with Characters and Variables tabs; Characters tab has full CRUD (add, edit, delete with usage warnings), name uniqueness validation, color picker, inline forms
+  - `src/components/editor/Toolbar.tsx` - Added `onProjectSettings` prop and "Project Settings" button to the right side of the toolbar
+  - `src/app/editor/[projectId]/FlowchartEditor.tsx` - Added `characters` and `variables` state management, `showSettings` modal state, usage count helpers (`getCharacterUsageCount`, `getVariableUsageCount`), and ProjectSettingsModal rendering
+- **Learnings for future iterations:**
+  - The ProjectSettingsModal receives `onCharactersChange` and `onVariablesChange` callbacks that directly set state in FlowchartEditor. When save is implemented, it should read from this state.
+  - The Variables tab is a read-only placeholder in US-056; US-057 will implement the full CRUD for variables using the same patterns (inline forms, validation, delete warnings).
+  - Modal pattern: fixed inset-0 z-50 with backdrop click to close, max-w-2xl for settings modals (larger than max-w-md used for simple dialogs).
+  - Character usage count checks dialogue nodes for `data.characterId`; variable usage count checks both variable nodes and edge conditions.
+  - The `randomHexColor()` utility picks from a curated list of 12 vibrant colors for character defaults.
+  - No browser testing tools are available; manual verification is needed.
