+  <files>src/lib/server/db/schema.ts</files>
+  <action>
+Add tags table and entry_tags junction table to schema.ts:
+
+1. Create `lower()` SQL helper function for case-insensitive indexing:
+```typescript
+import { sql, SQL } from 'drizzle-orm';
+import { AnySQLiteColumn } from 'drizzle-orm/sqlite-core';
+
+export function lower(column: AnySQLiteColumn): SQL {
+  return sql`lower(${column})`;

+  id: text('id').primaryKey(),
+  name: text('name').notNull(),
+  createdAt: text('created_at').notNull().$defaultFn(() => new Date().toISOString()),

+  tagId: text('tag_id').notNull().references(() => tags.id, { onDelete: 'cascade' }),
+}, (t) => [
+  primaryKey({ columns: [t.entryId, t.tagId] }),

+
+4. Add type exports:
+```typescript
+export type Tag = typeof tags.$inferSelect;
+export type NewTag = typeof tags.$inferInsert;
+export type EntryTag = typeof entryTags.$inferSelect;
+```
+

+Add TagRepository interface and implementation after ImageRepository:

+1. Import new schema tables:

+  getById(id: string): Tag | undefined;
+  getByEntryId(entryId: string): Tag[];

+
+3. Implement SQLiteTagRepository:
+- `findOrCreate(name)`:
+  - Normalize: `name.trim()`
+  - Query with `sql\`lower(${tags.name}) = lower(${normalizedName})\``
+  - If exists, return it
+  - If not, insert with nanoid() and return
+
+- `getAll()`:
+  - Select all from tags ordered by name ASC
+
+- `getById(id)`:
+  - Simple select where eq(tags.id, id)
+
+- `getByEntryId(entryId)`:
+  - Join entry_tags with tags where entryId matches
+  - Return Tag[] (the tag objects, not junction records)
+
+- `updateEntryTags(entryId, tagNames)`:
+  - Delete all from entry_tags where entryId matches
+  - For each tagName: findOrCreate tag, then insert into entry_tags
+
+4. Export singleton:
+```typescript
+export const tagRepository: TagRepository = new SQLiteTagRepository();
+```
+
+Import `sql` from 'drizzle-orm' for case-insensitive queries.
+  </action>

+Add two new form actions to the existing actions object:

+togglePin: async ({ request }) => {
+  const formData = await request.formData();
+  const id = formData.get('id')?.toString();
+
+  if (!id) {

+  <files>src/lib/components/EntryCard.svelte, src/lib/components/EntryList.svelte</files>
+  <action>
+**EntryCard.svelte changes:**
+
+1. Add state for due date editing:
+```typescript
+let editDueDate = $state(entry.dueDate || '');
+```
+
+2. Sync dueDate with entry on collapse (add to existing $effect):
+```typescript
+$effect(() => {
+  if (!expanded) {
+    // ... existing syncs
+    editDueDate = entry.dueDate || '';
+  }
+});
+```
+
+3. Add async function for pin toggle (similar to debouncedSave pattern):
+```typescript
+async function handleTogglePin() {
+  const formData = new FormData();
+  formData.append('id', entry.id);
+
+  await fetch('?/togglePin', {
+    method: 'POST',
+    body: formData
+  });
+
+  await invalidateAll();
+}
+```
+
+4. Add async function for due date change:
+```typescript
+async function handleDueDateChange(e: Event) {
+  const input = e.target as HTMLInputElement;
+  editDueDate = input.value;
+
+  const formData = new FormData();
+  formData.append('id', entry.id);

+
+  await fetch('?/updateDueDate', {
+    method: 'POST',
+    body: formData
+  });
+
+  await invalidateAll();
+}
+```
+
+5. In collapsed view header (after the expand arrow), add pin indicator:
+```svelte
+{#if entry.pinned}
+  <svg class="w-4 h-4 text-yellow-500" fill="currentColor" viewBox="0 0 20 20">
+    <path d="M5 4a2 2 0 012-2h6a2 2 0 012 2v3.586l1.707 1.707A1 1 0 0117 10v1a1 1 0 01-1 1h-4v5a1 1 0 11-2 0v-5H6a1 1 0 01-1-1v-1a1 1 0 01.293-.707L7 7.586V4z" />
+  </svg>
+{/if}
+```
+
+6. In collapsed view, show due date if set (near type badge):
+```svelte
+{#if entry.dueDate}
+  <span class="text-xs text-gray-500">{entry.dueDate}</span>
+{/if}
+```
+
+7. In expanded view, add pin button and due date picker (in the flex row with type and delete):
+```svelte
+<div class="flex items-center gap-3">
+  <button
+    type="button"
+    onclick={handleTogglePin}
+    class="p-2 rounded-lg hover:bg-gray-100 {entry.pinned ? 'text-yellow-500' : 'text-gray-400'}"

+
+  <div>

+    />
+  </div>
+</div>
+```
+
+**EntryList.svelte changes:**
+
+1. Separate entries into pinned and unpinned:
+```typescript
+let pinnedEntries = $derived(entries.filter(e => e.pinned));
+let unpinnedEntries = $derived(entries.filter(e => !e.pinned));
+```
+
+2. Render pinned section first if there are any:
+```svelte
+{#if pinnedEntries.length > 0}
+  <div class="mb-4">
+    <h2 class="text-sm font-medium text-gray-500 uppercase tracking-wide mb-2 px-4 md:px-0">Pinned</h2>

+<style>
+  :global(.tag-input) {
+    --sv-bg: white;
+    --sv-border: 1px solid #e5e7eb;
+    --sv-border-radius: 0.5rem;
+    --sv-min-height: 42px;
+  }
+</style>
+```
+
+**Update EntryCard.svelte:**
+
+1. Import TagInput and Tag type:
+```typescript
+import TagInput from './TagInput.svelte';
+import type { Tag } from '$lib/server/db/schema';
+```
+
+2. Add availableTags prop to Props interface:
+```typescript
+interface Props {
+  entry: EntryWithImages & { tags: Tag[] };
+  availableTags: Tag[];
+}
+
+let { entry, availableTags }: Props = $props();
+```
+
+3. Add state for tag editing:
+```typescript
+let editTags = $state<Tag[]>(entry.tags || []);
+```
+
+4. Sync tags with entry on collapse:
+```typescript
+$effect(() => {
+  if (!expanded) {
+    // ... existing syncs
+    editTags = entry.tags || [];
+  }
+});
+```
+
+5. Add function to handle tag changes:
+```typescript
+async function handleTagsChange(newTags: Tag[]) {
+  editTags = newTags;
+
+  // Save immediately (no debounce for tags)
+  const formData = new FormData();
+  formData.append('id', entry.id);
+  formData.append('tags', JSON.stringify(newTags.map(t => t.name)));
+
+  await fetch('?/updateTags', {
+    method: 'POST',
+    body: formData
+  });
+
+  await invalidateAll();
+}
+```
+
+6. Display tags in collapsed view (after type badge):
+```svelte
+{#if entry.tags?.length > 0}
+  <div class="flex flex-wrap gap-1 mt-1">
+    {#each entry.tags.slice(0, 3) as tag}
+      <span class="text-xs px-2 py-0.5 bg-gray-100 text-gray-600 rounded-full">{tag.name}</span>
+    {/each}
+    {#if entry.tags.length > 3}
+      <span class="text-xs text-gray-400">+{entry.tags.length - 3}</span>
+    {/if}
+  </div>
+{/if}
+```
+
+7. Add TagInput in expanded view (after type selector, before delete button):
+```svelte
+<div>
+  <label class="block text-sm font-medium text-gray-700 mb-1">Tags</label>
+  <TagInput
+    {availableTags}
+    selectedTags={editTags}
+    onchange={handleTagsChange}
+  />
+</div>
+```
+
+**Update +page.svelte:**
+
+Pass allTags to EntryList, then from EntryList to EntryCard. Or simpler - pass directly:
+
+1. Update EntryList.svelte to accept and pass availableTags:
+```typescript
+interface Props {
+  entries: EntryWithImages[];
+  availableTags: Tag[];
+}
+let { entries, availableTags }: Props = $props();
+```
+
+And pass to each EntryCard:
+```svelte
+<EntryCard {entry} {availableTags} />
+```
+
+2. Update +page.svelte to pass allTags:
+```svelte
+<EntryList entries={data.entries} availableTags={data.allTags} />
+```
+
+Import Tag type if needed for type checking.

+  <verify>Run `npm run dev`, test:
+1. Expand an entry - TagInput appears
+2. Type a tag name - autocomplete shows matching existing tags
+3. Select existing tag - appears as chip
+4. Type new tag and press Enter - tag created
+5. Click X on tag chip - tag removed
+6. Collapse and expand - tags persist</verify>
+  <done>TagInput component with Svelecte works, shows autocomplete, allows creation, displays tags on collapsed entries</done>

+1. `npm run check` passes
+2. Svelecte package installed and loads correctly
+3. Tag autocomplete shows all existing tags
+4. User can add tags (existing or new) to entries
+5. User can remove tags by clicking X
+6. Tags display on collapsed entry cards
+7. Case-insensitive: typing "Work" matches existing "work" tag

+<success_criteria>
+- User can add multiple tags to entry via Svelecte input (TAG-01)
+- User can remove tags by clicking X on chips (TAG-02)
+- Autocomplete shows matching existing tags as user types (TAG-03)
+- Existing tags matched case-insensitively (TAG-04)
+- Tags visible on collapsed entry cards (max 3 with +N indicator)
