# Issue #14: Preset configurations

**Status:** COMPLETED
**Issue:** https://git.shahondin1624.de/llm-multiverse/llm-multiverse-ui/issues/14
**Branch:** `feature/issue-14-preset-configs`

## Acceptance Criteria

- [x] Save current config as a named preset
- [x] Load preset from a list
- [x] Delete custom presets
- [x] 2-3 built-in default presets shipped:
  - "Strict mode" — no overrides, restricted tools (FS Write, Run Shell, Run Code, Package Install disabled)
  - "Research only" — limited tool set for read-only operations (Memory Write, FS Write, Run Code, Run Shell, Package Install disabled)
  - "Full access" — all overrides relaxed (OverrideLevel.ALL), no tools disabled
- [x] Presets persisted in localStorage
- [x] Built-in presets cannot be deleted

## Implementation

### New Files
- `src/lib/stores/presets.svelte.ts` — preset store with built-in presets and localStorage persistence for custom presets

### Modified Files
- `src/lib/components/ConfigSidebar.svelte` — added preset selector section at the top with load, save, and delete functionality

### Key Decisions
- Built-in presets are hardcoded constants, not stored in localStorage
- Custom presets stored under `llm-multiverse-presets` localStorage key
- Overwriting a custom preset with the same name is allowed; overwriting built-in presets is not
- Preset config uses a plain interface (`PresetConfig`) rather than protobuf types for clean serialization
- Preset section placed at the top of the sidebar before Override Level, matching the issue instructions
