Typefaces

The catalog's own faces. A screen composed into a template is drawn in that template's typefaces.

• Plus Jakarta SansHeadings: Plus Jakarta Sans 700, 36px/1.15, -0.02em
• Plus Jakarta SansBody: Plus Jakarta Sans 400 16px/1.5

Patterns

• floating rounded content card on tinted canvas
• large page title
• dismissible tip banner
• inline 'new task' row with shortcut hint
• task rows with list breadcrumb subtitle
• emoji-labelled nested lists in sidebar
• full-height scenic image panel
• active nav edge marker

States it is designed for

• first run (tip + three starter tasks)
• empty inbox (friendly 'Inbox zero' message on the card)
• adding task (inline input)
• completed with undo
• task with due date and assignee chips
• filter applied (chip under title)
• offline (local-first; sync badge shows pending changes)
• image failed to load (panel shows soft gradient)

Who it is for

• individuals organising work and life
• small teams
• students

Layout

1. left sidebar (~160px) on tinted canvas: Inbox (active with coloured right-edge bar), Today, Tasks, Messages; 'Recent'; 'Lists' with emoji-labelled items and collapsible Work/Personal groups with nested lists; bottom avatar
2. centre card (rounded, ~430px min): filter icon top-right, 36px 'Inbox' title, tip banner (icon, text, open and close buttons), 'New task' row with shortcut chip, task rows (checkbox, title, list subtitle, avatar, details icon)
3. right panel: rounded full-height scenic image
4. at <1100px the image panel hides; at <768px sidebar becomes a drawer and the card goes full width

Palette

Serene and personal; a quiet canvas beside a dreamy landscape.

As vibld’s tokens

The palette on the fifteen colour tokens vibld styles a project with, each text colour on the fill it is read on. Marked tokens are solved from the palette, because no swatch held that role at 4.5:1.

Type scale

Display

Plus Jakarta Sans 700, 36px/1.15, -0.02em

Body

Plus Jakarta Sans 400 16px/1.5

Sidebar 15px 500; task subtitles 13px muted with a small list icon; shortcut chip 12px mono-style in a pill.

Spacing and imagery

Relaxed: card 32px padding, 16px radius, no border, 0 1px 3px shadow; tip banner 12px radius; task rows 44px with 12px gap; image panel 16px radius with 8px outer gutter.

One large, softly lit landscape photo (dunes, water, moon-like light) in its own panel, decorative only; emoji as list icons; round initial avatars.

Components

• Sidebar (NavItem with EdgeMarker, CollapsibleListGroup, EmojiListItem)
• InboxCard
• TipBanner (open, dismiss)
• NewTaskRow with ShortcutChip
• TaskRow (Checkbox, title, ListBreadcrumb, Avatar, DetailsButton)
• FilterMenu
• ScenicPanel
• TaskDetailDrawer

Interactions

• Ctrl+N or clicking 'New task' turns the row into an input; Enter adds and keeps focus for the next
• checking a task strikes it through and slides it out after 1s (undo toast)
• drag tasks onto a sidebar list to file them (dnd-kit)
• tip banner dismiss persists; open arrow goes to a short guide
• details icon opens a right drawer over the image panel
• sidebar groups collapse with chevrons

Data

• Task{id, title, notes, list_id|null, done bool, done_at, due_on, assignee, position, created_at, updated_at}
• List{id, name, emoji, group (work|personal), position}
• UiPrefs{tip_dismissed bool, collapsed_groups string[]}

Guardrails

Experience

• New tasks land in Inbox by default; filing into lists is optional.
• Keep the add-task input always one keystroke away and show the shortcut.
• Provide undo for completion instead of a confirmation dialog.
• Show each task's list as a subtle subtitle so context is never lost.
• The image panel is decoration only; hide it before it squeezes the card.

Accessibility

• Task list is a list of items with native checkboxes labelled by the task title.
• Active nav uses aria-current and the edge marker plus bolder text.
• Tip banner is a region with a heading; dismiss has a label.
• Image panel has empty alt and is aria-hidden.
• Drag-to-list has a keyboard alternative ('Move to…' menu).

Security

• Validate imported/exported JSON with zod before loading.
• Escape task titles and notes when rendering; render notes markdown with a safe renderer.
• Wrap storage access in try/catch and never store secrets locally.

Build prompt

The baseline every prompt in the catalog assumes, then this design’s own ten sections, from goal to guardrails.

Copy the baseline and build prompt

### How to use these prompts
Paste an entry's build prompt into your coding agent as the first message. Each prompt names its own stack, tokens and acceptance criteria; the rules below apply to all of them and can be prepended once per project.

### Engineering baseline
- TypeScript strict mode, no `any`, small typed components, feature folders, and one source of truth for design tokens (CSS variables consumed by Tailwind).
- Validate every input with a shared zod schema on the client and again on the server or edge function. Never trust client-side checks alone.
- Show loading, empty and error states for every async view. Surface errors in plain language with a retry, and log details to the console in development only.
- Keep secrets out of the bundle. Only publishable keys (for example a Supabase anon key) belong in client code; service-role keys, API keys and webhooks live in server or edge-function environment variables.

### Data and auth baseline (full-stack entries)
- Enable Row Level Security on every table before inserting data. Default-deny, then add owner-scoped policies (`auth.uid() = user_id`) and explicit role checks for admin views.
- Store roles in a separate table checked by a security-definer function, never in a user-editable profile field.
- Upload files to private storage buckets with size and MIME limits, and serve them through signed URLs.
- Rate-limit public endpoints (forms, auth, AI calls) and add a honeypot field or captcha to anonymous forms.
- Take payments through a hosted checkout and verify webhooks by signature. Never handle raw card data.

### Accessibility and UX baseline
- Target WCAG 2.2 AA: 4.5:1 contrast for normal text and 3:1 for large text, input borders, focus rings and meaningful icons or chart lines. Every palette in this catalog lists its verified pairs; re-check with a contrast tool after any colour change.
- Keep body text at 16px or larger with 1.5 line height, nothing below 12px, no light weights under 24px, and uppercase only for short labels.
- Give every interactive element a visible focus ring, full keyboard support, semantic landmarks, labelled form fields, and alt text on meaningful images.
- Respect `prefers-reduced-motion` for every animation. Give drag-and-drop and carousels keyboard and button alternatives.
- Build mobile-first and test at 375px, 768px and 1280px.

### Content guardrails
- Use original copy, fictional sample data and placeholder or licensed imagery. Do not reuse another product's name, logo, screenshots or marketing text.
- Label demo testimonials and metrics as samples. Collect the minimum personal data the feature needs.

### SaaS screen baseline
- Design every screen for its full set of states: first-run empty, loading skeleton, partial data, error with retry, permission-denied, and success feedback. Each entry lists the states its screen needs.
- Keep destructive actions (delete, revoke, downgrade, remove member) behind a confirmation that names the object, and prefer undo over a second dialog where the action is reversible.
- Enforce authorisation on the server for every action a screen exposes. Hiding a button is not access control; check the role again in the API or RLS policy.
- Never show secrets (API keys, tokens) in full after creation. Show them once, then mask them, and offer rotate and revoke.
- Keep the app shell (navigation, workspace switcher, account menu) consistent across screens, and preserve filters, sort and scroll position when the user navigates back.

### Goal
Build **Plumtide**, a local-first personal task manager focused on its Inbox. New tasks land here; users check them off, file them into emoji-labelled lists and open details. A scenic image panel on wide screens gives the app a calm, personal feel.

### Stack
React 18 + TypeScript + Vite, Tailwind CSS, shadcn/ui (Checkbox, Sheet, DropdownMenu, Collapsible, Toast), lucide-react, dnd-kit, Motion, date-fns, zod. State in a reducer persisted to IndexedDB (with an in-memory fallback). No backend.

### Pages & layout
1. **Shell**: sidebar, centre card, image panel.
2. **/inbox** (this screen), **/today**, **/lists/:id** sharing the same card layout.
3. **Task detail drawer**.
4. Responsive per the layout breakpoints.

### Design system
- Colors: `--bg: #f5f5f8` (canvas), `--card: #fbfbfd` (card surface), `--fg: #1d1b22` (primary text), `--muted: #625f6d` (secondary text), `--marker: #d8343b` (active marker), `--tip-bg: #efedfa` (tip banner fill), `--tip-fg: #5040b8` (tip text), `--check: #858291` (checkbox border), `--row: #f0eff4` (new-task row fill), `--avatar: #0a84d6` (avatar).
- Fonts: Plus Jakarta Sans 700, 36px/1.15, -0.02em for headings; Plus Jakarta Sans 400 16px/1.5 for body. Sidebar 15px 500; task subtitles 13px muted with a small list icon; shortcut chip 12px mono-style in a pill.
- Spacing: Relaxed: card 32px padding, 16px radius, no border, 0 1px 3px shadow; tip banner 12px radius; task rows 44px with 12px gap; image panel 16px radius with 8px outer gutter.
- Radius: 16px card and image panel, 12px tip banner, 6px checkboxes, full pills for chips.
- Shadows: card 0 1px 3px rgba(29,27,34,0.06) only.
- Motion: completion slide-out 200ms after 1s; drawer 200ms; reduced motion removes slides.

### Components & interactions
Sidebar, NavItem, EdgeMarker, CollapsibleListGroup, EmojiListItem, InboxCard, TipBanner, NewTaskRow, ShortcutChip, TaskRow, FilterMenu, ScenicPanel, TaskDetailDrawer, UndoToast.

Interactions: Ctrl+N or clicking 'New task' turns the row into an input; Enter adds and keeps focus for the next; checking a task strikes it through and slides it out after 1s (undo toast); drag tasks onto a sidebar list to file them (dnd-kit); tip banner dismiss persists; open arrow goes to a short guide; details icon opens a right drawer over the image panel; sidebar groups collapse with chevrons.

States to build: first run (tip + three starter tasks); empty inbox (friendly 'Inbox zero' message on the card); adding task (inline input); completed with undo; task with due date and assignee chips; filter applied (chip under title); offline (local-first; sync badge shows pending changes); image failed to load (panel shows soft gradient).

### Data & state
Seed three starter tasks in a 'Getting started' list (connect a calendar, try the phone app, send feedback) plus sample lists (This week, Meeting notes, Groceries, Reading list, Habits). Positions use fractional indexing for drag reorder. Export/import JSON from settings.

Model: `Task{id, title, notes, list_id|null, done bool, done_at, due_on, assignee, position, created_at, updated_at}`; `List{id, name, emoji, group (work|personal), position}`; `UiPrefs{tip_dismissed bool, collapsed_groups string[]}`.

### Accessibility
Task list is a list of items with native checkboxes labelled by the task title. Active nav uses aria-current and the edge marker plus bolder text. Tip banner is a region with a heading; dismiss has a label. Image panel has empty alt and is aria-hidden. Drag-to-list has a keyboard alternative ('Move to…' menu).
Verified contrast: body text on card: #1d1b22 on #fbfbfd = 16.49:1; muted subtitle: #625f6d on #fbfbfd = 6.02:1; sidebar text on canvas: #1d1b22 on #f5f5f8 = 15.66:1; tip text on tip fill: #5040b8 on #efedfa = 6.57:1; checkbox border: #858291 on #fbfbfd = 3.63:1; active marker: #d8343b on #f5f5f8 = 4.31:1; placeholder in new-task row: #625f6d on #f0eff4 = 5.44:1.

### Security
Validate imported/exported JSON with zod before loading. Escape task titles and notes when rendering; render notes markdown with a safe renderer. Wrap storage access in try/catch and never store secrets locally. No server; all data stays on the device. Validate any imported file and cap its size (2 MB).

### Performance & SEO
Bundle under 150 kB gzipped; serve the scenic image as responsive AVIF/WebP with width descriptors and lazy decoding; skip loading it below 1100px. Set title and meta description on the public landing route; app routes noindex.

### Guardrails
- New tasks land in Inbox by default; filing into lists is optional.
- Keep the add-task input always one keystroke away and show the shortcut.
- Provide undo for completion instead of a confirmation dialog.
- Show each task's list as a subtle subtitle so context is never lost.
- The image panel is decoration only; hide it before it squeezes the card.
- Write all copy fresh; use invented people, companies and numbers only. No real brands, logos, wordmarks or third-party product names anywhere in the UI or seed data.
- Do not trace or copy any existing product's layout assets, icons or illustrations; draw generic ones.
- Acceptance criteria:
  - [ ] Tasks can be added with the keyboard shortcut and Enter
  - [ ] Completing a task offers undo
  - [ ] Dragging or 'Move to…' files a task into a list
  - [ ] Data survives reload and works offline
  - [ ] Image panel hides at narrow widths without layout jumps
