+# Product
+
+
+
+## Platform
+
+web
+
+## Users
+
+Primary: an application developer, mid-feature, who has just written UI and needs to add,
+find, or verify translation keys and get back to coding. They already know the codebase and
+the key they are looking for. Interruption cost is the dominant concern.
+
+Secondary (real, must not be blocked):
+
+- Translators and reviewers working through `new` / `stale` entries a locale at a time,
+ judging wording rather than moving fast.
+- The i18n owner, accountable for translation health across collections before a release —
+ hunting gaps, stale entries, and protected-term violations.
+
+## Product Purpose
+
+LingoTracker manages translation resources for apps using the Transloco library. The Tracker
+web UI is its visual surface: browse a collection's folder tree, search across keys and
+values, filter by locale and status, edit translations, and trigger auto-translation.
+
+Success is a developer resolving a translation question in the UI faster than they could by
+hand-editing JSON — and a release going out with no `new` or `stale` entries left behind.
+
+## Positioning
+
+Translations live as plain JSON files in the user's own repository, next to the code, with
+metadata (MD5 checksums, status) in sibling files. There is no hosted service and no
+database: every change is a Git diff a teammate can review in a normal pull request. The
+UI is a lens onto those files, not a system of record that owns them.
+
+## Operating Context
+
+- Launched locally via `npx lingo-tracker-app`; the API (default port 3030) serves the UI and
+ reads and writes the developer's working tree.
+- The UI is one of three interfaces over the same core library, alongside a CLI (used
+ interactively and in CI/CD) and a REST API. Behavior must not contradict the CLI.
+- Work is organized into **collections** — resources grouped by team, feature, or domain.
+ Some collections are **read-only** (e.g. component-library translations vendored under
+ `node_modules`).
+- Routes: `/collections` (manager), `/browser/:collectionName` (the main working surface),
+ `/settings`.
+
+## Capabilities and Constraints
+
+Confirmed capabilities in the UI:
+
+- Folder-tree sidebar over dot-delimited resource keys (`apps.common.buttons.ok`).
+- Search across keys and values; filter by locale and by status.
+- Compact / expanded density modes; view preferences persisted per collection.
+- Translation editor dialog with similar-translation suggestions as you type.
+- One-click auto-translation (Google Translate), preserving ICU placeholders and Transloco
+ variables.
+- Collection create/edit; read-only collections are protected across CLI, API, and UI.
+- Settings page manages the protected-terms list: an alphabetical list with inline rename,
+ staged add/remove, and an explicit save, backed by a standalone JSON file.
+- Comment and tag popovers; indexing overlay during long operations.
+
+Constraints:
+
+- **Local-first, no accounts.** Single machine, single user. No auth, no multi-user
+ presence, no remote sync state to design around.
+- **Read-only collections must always be unmistakable** in the UI.
+- **The Tracker UI is itself fully localized** with Transloco and dogfoods LingoTracker.
+ Every user-visible string goes through the resource workflow — no hardcoded copy. Shipped
+ UI locales: `en`, `de`, `es`, `fr-ca`, `ja`, `ru`. Layouts must survive long German and
+ Russian strings and Japanese line-breaking.
+- Angular 20 standalone components, Angular Material, NgRx Signals, OnPush change detection.
+- Terminology is domain vocabulary and is not up for renaming: collection, resource, key,
+ locale, base locale, bundle, glossary, protected term, and the status lifecycle
+ `new` → `translated` → `stale` → `verified`.
+
+## Brand Commitments
+
+- Name: **LingoTracker**. Tagline: "Effortlessly Track, Validate, and Manage Your
+ Translations."
+- The **watercolor visual identity is binding**, not placeholder: warm parchment
+ backgrounds, coral/vermillion primary, deep sky-blue secondary, and the watercolor accent
+ palette in `src/styles/tokens.scss`. Nunito for all text; Grechen Fuemen reserved for the
+ LingoTracker brand title only.
+- Logo assets: `src/assets/logo.png`, `src/assets/logo-dark.png`,
+ `src/assets/lingo-tracker-favicon-cropped.png`.
+- Light and dark themes both ship.
+
+## Evidence on Hand
+
+- Real product docs: repo `README.md`, `ROADMAP.md`, `docs/` (auto-translation, glossary,
+ protected terms, validate, bundle type generation), and a docs site under `docs-site/`.
+- Real translation data: the Tracker's own `src/assets/i18n/*.json` across six locales.
+- The project is described as stable and "currently being validated in an enterprise
+ application." There are **no** named customers, testimonials, logos, benchmarks, pricing,
+ or usage numbers — future work must not invent any.
+
+## Product Principles
+
+1. **The files are the truth.** The UI never becomes a source of state the repository cannot
+ reproduce; every action ends as a reviewable Git diff.
+2. **Don't break the developer's flow.** The primary user arrived with a key in mind and
+ wants to leave; the shortest path from landing to that key wins over browsing elegance.
+3. **Status is the spine.** `new` / `translated` / `stale` / `verified` is how every user
+ decides what to touch next, and it must be legible at a glance at any density.
+4. **Never let a destructive or locked state be a surprise.** Read-only collections,
+ protected terms, and deletions announce themselves before the fact.
+5. **Practice what it preaches.** The UI is localized, ICU-correct, and layout-safe in every
+ locale it ships — it is its own reference implementation.
+
+## Accessibility & Inclusion
+
+No product-specific standard has been established yet — recorded as undecided. Existing code
+shows deliberate `aria-labelledby` use on settings sections, so the incumbent baseline is
+Angular Material semantics plus explicit landmark labeling; future work should not regress
+below that.
