New BrandOverviewComponent, mounted at the top of the existing
Branding section page (no route/schema/business-logic changes):
- Completion ring + recommended next step + last-modified timestamp,
computed from real facade signals (branding.logoUrl/faviconUrl/
socialImageUrl, theme.palette, theme.typography, lastSavedAt) -
nothing fabricated.
- Brand Health checklist (6 items: logo, favicon, colors, typography,
social image, accessibility) - icon+text, never color alone.
- Color palette preview: 10 swatches from the real ThemePaletteConfig
(primary/secondary/accent/success/warning/danger/backgrounds/text/
border), each with a readable label.
- Real WCAG contrast check (contrast.util.ts, relative-luminance
formula) between configured text and background colors - shows an
inline warning when below 4.5:1, never blocks publishing.
- Typography live preview using the configured heading/body font
families and base size.
- Social share preview card (Open Graph-style) using the existing
socialImageUrl + seo.default.title/description, with an explicit
empty state when no image is set yet.
Scope cut from the full brief given this session's cost already well
over budget entering this sprint - see Known limitations in the final
report (no multi-variant logo/favicon management, no live responsive
device preview, no new media library/asset picker; all reuse the
existing single-logo/single-favicon fields and image-field upload
component as-is).
Could not verify live in-browser this sprint: port 4200 is held by
another chat's dev server. Verified via `tsc --noEmit` (clean) and
manual template/binding review only; one binding (`--pct` custom-
property style binding) was replaced with a plain computed string to
remove an unverifiable risk rather than ship it unverified.
