Second phase of the hero canvas editor (see HERO_EDITOR.md).
- new lib/heroLayout.js: shared defaultLayout/buildOverlay/heroBackground/
parseLayout used by both the portal and the editor (Portal refactored onto it)
- new admin view HeroEditor.jsx at /admin/hero (+ sidebar nav + route):
- live canvas preview (16:9) rendering the draft via HeroElement
- background panel: image upload (/admin/uploads, >1MB warning), 3x3 position
grid, overlay opacity slider — all update the canvas in real time
- debounced (800ms) auto-save to hero_layout_draft
- Publish (writes hero_layout + draft), Preview (opens /?preview=1), Revert
- Portal: ?preview=1 renders the draft via the admin settings endpoint, with a
"showing unpublished draft" banner; normal load renders the published layout
No schema/dep changes. Verified end to end: overlay/position update the canvas,
auto-save writes the draft, publish updates the live portal, preview shows the
draft while the public page shows live. Element drag/properties land in Phase 3.

Build contract for the WYSIWYG portal-hero editor on hero-feature, derived
from the design doc and corrected against the codebase:
- public settings is a whitelist (getPublic/PUBLIC_KEYS), so hero_layout must
be added there — the doc's "no backend changes" was wrong
- moon is the reusable MoonDot component; route vs nav live in App.jsx vs
AdminLayout.jsx; admin content is 1000px (canvas scales to fit)
Locked decisions: full v1, buttons as a first-class element type, pre-populate
the current hero on first run, native Pointer Events for drag. Phased plan
with per-phase exit checks. No schema change (JSON in settings).
