		9	+	- DNS prefetch: Added capability to prefetch DNS for links to speed up future requests
		10	+	- Page cache (bfcache): Enabled WebKit back/forward cache for instant navigation
		11	+	- Smooth scrolling: Enabled WebKit smooth scrolling for better UX
		12	+	- JSON Schema: Auto-generated config schema for IDE autocompletion and validation
		13	+	- Parallel cache loading: Zoom, certificate, and fuzzy caches load concurrently at startup (<100ms target)
		14	+	- Certificate validation cache: In-memory cache for TLS certificate decisions with graceful shutdown flushing
		15	+
		16	+	### Changed
		17	+	- Database performance: Enabled WAL mode with optimized PRAGMAs (64MB cache, memory-mapped I/O, 5s busy timeout) for 70k reads/sec, 3.6k writes/sec
		18	+	- Zoom performance: In-memory cache eliminates database reads during page transitions
		19	+	- History writes: Batched writes with background processor (flush every 5s or 50 items) to reduce I/O overhead
		20	+	- BREAKING: Keyboard shortcuts: All shortcuts now use `ctrl+` instead of `cmdorctrl+`. Existing configs with `cmdorctrl` still work via backward compatibility. Delete `~/.config/dumber/config.json` to regenerate with new defaults.
		21	+	- Cache management: Graceful cache flushing on shutdown prevents data loss; startup timing instrumentation with performance warnings
		22	+
		23	+	### Fixed
		24	+	- Graceful shutdown deadlock: Resolved GTK main loop deadlock on Ctrl+Q by removing mutex locks and GTK calls after main loop exit
		25	+	- CSS provider error handling: Now properly handles errors from GTK CSS provider with logging
		26	+	- Cache operations: Added context timeouts to cache flush and history queue operations for graceful failure
		27	+	- Command typos now show proper error instead of opening in browser
		28	+	- History queue now uses buffered channel to prevent blocking on shutdown

	2	+
	3	+	A type-safe, high-performance caching layer for Dumber Browser that provides RAM-first access with asynchronous database persistence.
	4	+
	5	+	## Overview
	6	+
	7	+	The generic cache framework provides a consistent caching pattern across all Dumber Browser caches:
	8	+	- RAM-First: All reads from memory (no DB queries)
	9	+	- Async Writes: Updates happen immediately in cache, persisted asynchronously
	10	+	- Bulk Load: Load all data from DB at startup
	11	+	- Graceful Shutdown: Flush all pending writes on shutdown

	58	+
	59	+	## Usage Example
	60	+
	61	+	### 1. Implement DatabaseOperations
	62	+
	63	+	First, create a struct that implements the `DatabaseOperations[K, V]` interface:
	64	+
	65	+	```go
	66	+	package cache
	67	+
	68	+	import (
	69	+	"context"
	70	+	"github.com/bnema/dumber/internal/cache/generic"
	71	+	"github.com/bnema/dumber/internal/db"
	72	+	)
	73	+
	74	+	// ZoomDBOperations implements DatabaseOperations for zoom levels
	75	+	type ZoomDBOperations struct {
	76	+	queries db.DatabaseQuerier
	77	+	}
	78	+
	79	+	func NewZoomDBOperations(queries db.DatabaseQuerier) *ZoomDBOperations {
	80	+	return &ZoomDBOperations{queries: queries}
	81	+	}
	82	+
	83	+	func (z *ZoomDBOperations) LoadAll(ctx context.Context) (map[string]float64, error) {
	84	+	levels, err := z.queries.ListZoomLevels(ctx)
	85	+	if err != nil {
	86	+	return nil, err
	87	+	}
	88	+
	89	+	result := make(map[string]float64, len(levels))
	90	+	for _, level := range levels {
	91	+	result[level.Domain] = level.ZoomFactor
	92	+	}
	93	+	return result, nil
	94	+	}
	95	+
	96	+	func (z *ZoomDBOperations) Persist(ctx context.Context, key string, value float64) error {
	97	+	return z.queries.SetZoomLevel(ctx, key, value)
	98	+	}
	99	+
	100	+	func (z *ZoomDBOperations) Delete(ctx context.Context, key string) error {
	101	+	return z.queries.DeleteZoomLevel(ctx, key)
	102	+	}
	103	+	```
	104	+
	105	+	### 2. Create a Cache Instance
	106	+
	107	+	```go
	108	+	package cache
	109	+
	110	+	import "github.com/bnema/dumber/internal/cache/generic"
	111	+
	112	+	type ZoomCache struct {
	113	+	*generic.GenericCache[string, float64]
	114	+	}
	115	+
	116	+	func NewZoomCache(queries db.DatabaseQuerier) *ZoomCache {
	117	+	dbOps := NewZoomDBOperations(queries)
	118	+	return &ZoomCache{
	119	+	GenericCache: generic.NewGenericCache(dbOps),
	120	+	}
	121	+	}
	122	+	```
	123	+
	124	+	### 3. Use in Application Code
	125	+
	126	+	```go
	127	+	// At startup
	128	+	zoomCache := cache.NewZoomCache(dbQueries)
	129	+	if err := zoomCache.Load(ctx); err != nil {
	130	+	log.Fatalf("Failed to load zoom cache: %v", err)
	131	+	}
	132	+
	133	+	// Get (always from RAM, never hits DB)
	134	+	if zoomLevel, ok := zoomCache.Get("example.com"); ok {
	135	+	fmt.Printf("Zoom level: %.2f\n", zoomLevel)
	136	+	}
	137	+
	138	+	// Set (immediate in cache, async to DB)
	139	+	if err := zoomCache.Set("example.com", 1.5); err != nil {
	140	+	log.Printf("Failed to set zoom level: %v", err)
	141	+	}
	142	+
	143	+	// On shutdown
	144	+	if err := zoomCache.Flush(); err != nil {
	145	+	log.Printf("Failed to flush cache: %v", err)
	146	+	}
	147	+	```
	148	+
	149	+	## Performance Characteristics
	150	+
	151	+	\| Operation \| Latency \| Notes \|
	152	+	\|-----------\|-------------\|--------------------------------------------\|
	153	+	\| Load() \| ~2-50ms \| One-time at startup, bulk loads all data \|
	154	+	\| Get() \| <1µs \| sync.Map lookup, never touches DB \|
	155	+	\| Set() \| <1µs \| Returns immediately, DB write async \|
	156	+	\| Delete() \| <1µs \| Returns immediately, DB delete async \|
	157	+	\| List() \| ~10-100µs \| Iterates sync.Map, no DB access \|
	158	+	\| Flush() \| Varies \| Blocks until all async writes complete \|
	159	+
	160	+	## Thread Safety
	161	+
	162	+	All operations are thread-safe:
	163	+	- `sync.Map` provides lock-free concurrent reads and writes
	164	+	- `sync.WaitGroup` coordinates graceful shutdown
	165	+	- Database operations are serialized per key (last write wins)
	166	+
	167	+	## Testing
	168	+
	169	+	The framework includes comprehensive unit tests with a mock implementation:
	170	+
	171	+	```go
	172	+	import "github.com/bnema/dumber/internal/cache/generic"
	173	+
	174	+	func TestMyCache(t *testing.T) {
	175	+	mock := generic.NewMockDatabaseOperations[string, int]()
	176	+
	177	+	// Configure mock behavior
	178	+	mock.LoadAllFunc = func(ctx context.Context) (map[string]int, error) {
	179	+	return map[string]int{"key": 42}, nil
	180	+	}
	181	+
	182	+	cache := generic.NewGenericCache(mock)
	183	+
	184	+	// Test cache operations
	185	+	if err := cache.Load(context.Background()); err != nil {
	186	+	t.Fatal(err)
	187	+	}
	188	+
	189	+	val, ok := cache.Get("key")
	190	+	if !ok \|\| val != 42 {
	191	+	t.Errorf("Expected key=42, got %v, %v", val, ok)
	192	+	}
	193	+
	194	+	// Verify mock was called
	195	+	if count := mock.GetLoadAllCallCount(); count != 1 {
	196	+	t.Errorf("Expected LoadAll called once, got %d", count)
	197	+	}
	198	+	}
	199	+	```
	200	+
	201	+	## Design Decisions
	202	+
	203	+	### Why Generic?
	204	+
	205	+	Type safety and code reuse. The same cache implementation works for:
	206	+	- `Cache[string, float64]` (zoom levels)
	207	+	- `Cache[string, Shortcut]` (search shortcuts)
	208	+	- `Cache[string, CertValidation]` (TLS certificates)
	209	+
	210	+	### Why Async Persistence?
	211	+
	212	+	- Startup Performance: <500ms startup time requirement
	213	+	- UI Responsiveness: Never block user actions on DB writes
	214	+	- Write Coalescing: Multiple rapid updates to same key only persist latest value
	215	+
	216	+	### Why Bulk Load?
	217	+
	218	+	- Small datasets (10-100 entries typical)
	219	+	- Faster than incremental loading with query overhead
	220	+	- Simpler code: no cache miss logic needed
	221	+
	222	+	### Why sync.Map Instead of map + RWMutex?
	223	+
	224	+	- Lock-free reads in common case
	225	+	- Better performance under concurrent load
	226	+	- Standard library, battle-tested
	227	+
	228	+	## Limitations
	229	+
	230	+	- Not for large datasets: Loads entire dataset into RAM
	231	+	- No TTL/expiration: All entries cached indefinitely
	232	+	- No size limits: Assumes datasets fit comfortably in memory
	233	+	- Last write wins: No conflict resolution for concurrent updates
	234	+
	235	+	For Dumber Browser's use case (small configuration tables), these tradeoffs are acceptable.
	236	+
	237	+	## Future Enhancements
	238	+
	239	+	Potential improvements if needed:
	240	+	- [ ] Add metrics (cache hits, miss rate, persist latency)
	241	+	- [ ] Add TTL support for time-sensitive data
	242	+	- [ ] Add size-based eviction for large caches
	243	+	- [ ] Add batch persistence for write-heavy workloads
	244	+	- [ ] Add versioning/CAS for concurrent update detection
