## What
Makes `@shared` the single home for the Stirling brand logo assets.
Moves the editor's two logo sets — `classic-logo` + `modern-logo` (22
files: marks, wordmarks, favicons, login headers, PNGs) — out of
`editor/public/` into `shared/assets/brand/`, and adds a Storybook
**Brand/Logos** gallery.
## Why this shape (not a plain move)
The editor serves logos by **URL** from `public/` and switches
`classic`/`modern` by a **user preference** (`useLogoAssets`,
`manifest.json` / `manifest-classic.json`, `index.html` favicon links).
Rewiring all that to module imports would be a large, risky change to
the variant system.
Instead the editor keeps its variant system **unchanged** and just
sources the files from shared: `vite-plugin-static-copy` copies
`shared/assets/brand/{classic,modern}-logo/*` back to the served
`/{classic,modern}-logo` paths (the editor already uses this plugin for
pdfium/pdfjs assets). Single source of truth in shared, zero editor
code/manifest/markup changes.
## Verified
- **Build:** editor builds with both sets present at
`dist/{modern,classic}-logo/`; `manifest.json` + favicon refs resolve.
- **Dev:** the vite dev server serves the bridged paths —
`/modern-logo/logo512.png`,
`/modern-logo/StirlingPDFLogoNoTextDark.svg`,
`/classic-logo/favicon.ico` all return **HTTP 200** (the plugin's dev
middleware).
- Typecheck clean on core/proprietary/saas; prettier clean; `storybook
build` succeeds with the `Brand/Logos` gallery bundled.
- The portal's existing `@shared/assets` brand imports are untouched.
## Follow-ups (not in this PR)
- **Dedup:** `shared/assets/stirling-mark-*.svg` is byte-identical to
`brand/modern-logo/StirlingPDFLogoNoTextDark.svg`, and
`stirling-pdf-logo-*` is a near-twin of the modern wordmark. Reconciling
these (and re-pointing the portal) needs a designer eye on which
wordmark is canonical, so it's left out here to avoid changing the
portal's rendered logo.
- `editor/src/logo.svg` appears unused (no references) — candidate for
deletion separately.
# Description of Changes
Refactor frontend auth to the shared folder and hook it up to both the
portal and editor so they share the same system. Also adds various tasks
to help run the portal, including `task dev:portal` to spawn the portal
with the backend, and `task dev:portal:proxy` to spawn the editor,
portal and backend, and a reverse proxy (at localhost:3000) to allow you
to use both at once to simulate how this will actually be deployed,
allowing you to check whether the seamless transition between the two
actually works.
