--- paths: - "app/**" - "components/**" --- # Design Context & Design System Always use the `/frontend-design` skill for new UI. The conventions below are locked: deviating from them on existing pages is a regression. ## Users Swedish sole traders (enskild firma) and small business owners (aktiebolag) who manage their own bookkeeping. They are not accountants; they are professionals (consultants, freelancers, shop owners) who want to stay compliant without hiring one. They use Accounted in short, focused sessions: sending an invoice, categorizing bank transactions, filing a VAT declaration. Speed and clarity matter. ## Brand & Aesthetic **Editorial monochrome.** Paper-white surfaces, hairline borders, serif headlines. The interface should feel like a well-made instrument, considered, quiet, confident. Anti-references: enterprise software (SAP/Oracle density), neon SaaS coldness. - **Palette**: Achromatic foundation. Pure white background, warm beige (`40 11% 89%`) for chips / active sidebar / hover / secondary buttons. Achromatic primary (no cool tint). Semantic colors (`--success` sage, `--warning` ochre, `--destructive` terracotta) exist but are **data-only**: they appear in charts and financial numbers (positive/negative deltas), never as chrome backgrounds. In chrome, only `--destructive` survives. - **Typography**: Hedvig Letters Serif for display headings, Geist (sans) for body, forms, and tables. Hedvig is single-weight (400): do not apply `font-medium` to display text; its natural high-contrast strokes carry the weight. Tabular numbers everywhere financial data appears. - **Surfaces**: The page itself is a rounded panel (12px) floating on a warm-toned frame (`--frame`); the sidebar sits borderless on the frame. Cards sit flat on the page: no shadow, full-opacity hairline border (`border-border`), `rounded-lg` (8px). Card background matches page background; the border carries hierarchy. Dark mode drops the warm tint from secondary for a pure-gray mood shift; light mode keeps the beige. - **Spacing**: Generous whitespace. Dense data (tables, ledgers) uses tighter spacing but never feels cramped. - **Motion**: Functional, not decorative. No press-scale, no hover-lift, no spring overshoot. Hover state is a flat background shift (`bg-secondary/60`). `transition-colors duration-150` is the default. Stagger animations on list entry are fine. Respect `prefers-reduced-motion` (already wired). - **Icons**: Lucide: 15px in navigation, slightly larger in empty states. ## Design Principles 1. Clarity over cleverness: Swedish labels, obvious hierarchy. 2. Earned minimalism: remove what doesn't serve the task, keep compliance context. 3. Numbers are first-class: tabular-nums, alignment, positive/negative clarity. 4. Trust through consistency. 5. Speed is a feature: optimize for the 90-second session. ## Accessibility WCAG AA (4.5:1 text, 3:1 UI). Keyboard-navigable + visible focus rings. Respect `prefers-reduced-motion`. Color never sole state indicator. Touch targets ≥40px (44px for mobile-critical). Icon-only buttons need `aria-label`. ## Locked UI-migration conventions Decided during the 2026-07 concept work (dev_docs/ui_migration_plan.md); they apply system-wide and override anything below that conflicts. 1. **Frame layout.** The page is a rounded panel (12px) on a warm-toned frame (`--frame`). The panel keeps `--background`; the sidebar is borderless on the frame. 2. **Page title is exactly 24px/32px** Hedvig Letters Serif (`text-2xl leading-8` via PageHeader). 3. **Buttons are pills.** Radius 99px, default padding 7px 16px, 13px text. Set once in `components/ui/button.tsx`, app-wide, never per page. 4. **Table rows are one line.** Secondary info (descriptions, OCR, roles) belongs in the detail view or a click-popup, never as sub-rows in lists. 5. **Chips mark exceptions.** Normal states render as muted text; Badge only when the row deviates. Same chip on every row means the chip is wrong. 6. **Attention is one ochre sentence**, not a banner: the `.attn` pattern (12.5px, `--warning` tone, single line, optionally with an embedded action link). Max one per page. 7. **Help text lives behind a "?"** right after the H1: a small (17px) circular button opening a popover anchored at the button. No instructional copy in the page flow. 8. **One context picker per page, far right in the toolbar**: fiscal year or account/source as a chip-dropdown with a check on the active choice. A chip that looks like a picker must be a picker. 9. **The primary action lives in the page header**, right side. Multiple create paths collapse into a split button whose caret menu remembers the last-used mode (persisted in `user_preferences`, not localStorage). 10. **Confirm up front, don't comment afterwards.** Actions that post or send open a small confirm dialog describing the outcome ("Bokförs som verifikat A-217 ...") instead of writing outcome text into the page afterwards. 11. **Content lands with stagger.** `.stagger-enter` is the standard entry for list/table content, on server render and on client-fetch completion alike. 12. **Status colors are data, not chrome**: sage/ochre/terracotta only in numbers, exception chips and `.attn`. 13. **Overlays**: centered modal for create/confirm (template, assistant, confirmations, settings); right slide-over for reviewing an object (Granskning detail). Both with veil, Esc, and click-outside. 14. **Manual base, AI as opt-in.** Base flows work without AI; AI entry points are clearly labeled discrete choices (e.g. "Skapa med assistenten") and no AI suggestion posts without Granskning. 15. **Settings speak "Fönster"** (founder-chosen 2026-07-25, applies to every settings tab). Settings content is flat hairline rows, never boxed cards: `SettingsGroup` / `SettingsRow` / `SettingsSectionHeader` from `components/settings/SettingsRows.tsx`. Toggles are switches, not checkboxes. Saving is a sticky bar that fades in only when the form is dirty (`components/settings/SettingsFormWrapper.tsx`); no always-visible save button. The settings surface is a 920x680 modal (`components/settings/SettingsModal.tsx`); switching tabs inside it updates the URL shallowly via `history.replaceState` (`SettingsRail.tsx`), never `router.replace`, which would remount the modal. ## Design System Tokens **Spacing scale.** Only use Tailwind values `1, 2, 3, 4, 6, 8, 10, 12`. **Forbidden:** `2.5`, `5`, hardcoded pixels in page logic. | Token | Tailwind | Use for | |---|---|---| | 4 | `1` | icon padding | | 8 | `2` | tight inline gaps | | 12 | `3` | dense list rows, badge gaps | | 16 | `4` | default form / control / grid gap | | 24 | `6` | **card padding default** (`p-6`) | | 32 | `8` | **between page sections** (`space-y-8` on page root) | | 40 | `10` | hero spacing | | 48 | `12` | top of page after header | Compact metric cards (e.g. dashboard tiles, salary KPI row) use `p-4`. Detail cards use `p-6`. Never mix `p-5`. **Layout (frame layout).** - The dashboard wrapper is `bg-frame` (`--frame: 40 18% 96%` light, `0 0% 5%` dark). `
` is the page panel: `bg-background rounded-xl border border-border`, 10px margin against the frame, own inner scroll (`md:h-[calc(100vh-20px)] md:overflow-y-auto`). Defined once as `MAIN_PANEL_CLASS` in `app/(dashboard)/layout.tsx`; never restyle per page. - The panel is the desktop scroll container: `position: sticky` binds to it automatically; never assume `window` scroll on dashboard pages. Scroll reset on navigation lives in `MainContainer`. - Sidebar width: `md:w-64` (256px), borderless and transparent on the frame. Panel offset: `md:ml-64`. - Main container: `max-w-5xl mx-auto px-5 py-8 md:px-8 md:py-10` (via `components/dashboard/MainContainer.tsx`). - Page root: `
`. - Mobile keeps the pre-frame layout: full-width document flow, bottom nav; the panel styles are `md:`-gated. **Primitives: always use these, don't hand-roll.** | Need | Component | Notes | |---|---|---| | Page title + action | `components/ui/page-header.tsx` `PageHeader` | Use this, not bespoke `

` + `

` blocks. Drop the `description` prop when it just paraphrases the title. | | Data table, **page-level list** | `components/ui/dry-table.tsx` `TH_CLASS` / `TD_CLASS` on a plain ``, rows `hover:bg-secondary/35` | The concept list table: borderless, straight on the panel, 13px rows, hairline heads. This is what every migrated list page uses. Add `tabular-nums` to numeric cells. Hover-revealed row controls use `HOVER_REVEAL_CLASS` from the same file, never a hand-rolled `opacity-0 group-hover:opacity-100` (coarse pointers never hover, so the control would be unreachable on touch). | | Data table, **dialog or report view** | `components/ui/table.tsx` `Table / TableHeader / TableHead / TableRow / TableCell` | Header style is baked in: `text-[11px] font-medium uppercase tracking-wider text-muted-foreground`. Wrap in `` when the table is a card's primary content. `TableCell` is `px-4 py-3` on `text-sm`, so a page-level list built from this primitive comes out ~15% taller with a different hover tint: use the dry-table row above instead. | | Status indicator | `components/ui/badge.tsx` `` | Chips mark exceptions only: normal states (Aktiv, Bokförd, Betald-i-tid) render as muted text (`text-muted-foreground text-xs`); Badge is reserved for rows that deviate (Utkast, Förfallen, Ej bokförd). A table where every row carries the same chip is wrong. Variants: `default / secondary / success / warning / destructive / outline`. **Never** use raw Tailwind colors (`bg-blue-100`, `bg-emerald-500/10`, etc.) for status. Map status → variant via a small `Record` per feature. | | No-data state | `components/ui/empty-state.tsx` `EmptyState` | Don't hand-roll `
…
`. Preset variants exist (`EmptyInvoices`, `EmptyCustomers`, `EmptyTransactions`, etc.). | | Loading placeholder | `components/ui/skeleton.tsx` `` | Don't hand-roll `bg-muted rounded animate-pulse` divs. | | Inline help / formulas | `components/ui/info-tooltip.tsx` `InfoTooltip` | Hover-revealed; don't use always-visible info buttons. | | Fiscal year picker | `components/common/FyPicker.tsx` | The chip-dropdown context picker of convention 8 (wraps `ContextPicker`). `FiscalYearSelector` is the legacy pre-frame control: don't add new uses. Never use a raw ``. **Date formatting.** Two helpers in `lib/utils.ts`: - `formatDate(x)` → `2026-05-11` (ISO `yyyy-MM-dd`). Use for accounting data: transaction dates, invoice dates, payment dates, voucher dates. Aligns in tables, matches SIE/BFL convention. - `formatDateLong(x)` → `11 maj 2026` (Swedish long form). Use for metadata: when something was created, linked, verified, expires. Settings panels and audit displays. Never render raw `{x.invoice_date}` directly: always route through `formatDate()` for code consistency. **Currency.** `formatCurrency(n, currency?)` from `lib/utils.ts`. Default SEK. **Typography.** - Page title: use `PageHeader` (renders `font-display text-2xl leading-8 tracking-tight`, exactly 24px/32px, locked). Do not hand-roll an `

`. - Card title: `` for sections, default for primary cards. The primitive already drops `font-medium`: do not add it back. - Section divider header inside a page: `

`. - Headline number: `font-display text-xl tabular-nums`. No `font-medium`: Hedvig's natural weight carries the gravitas. - Display font (`font-display`, Hedvig Letters Serif) reserved for h1/h2/h3 and primary financial numbers. If a specific `font-display` numeral reads weak inside a compact metric card, override that call site with `font-sans tabular-nums` (Geist), better legibility on small numerals. **Forbidden / dead patterns.** - Page descriptions that paraphrase the page title (e.g. ``) → drop the description. - Two different status indicators on the same element (e.g. colored card border *and* Badge for status) → pick one (prefer Badge). - Mobile-specific `
