# Hero Section Admin Upgrade — Completion Report

## Status: ✅ Complete, tested, and integrated

The Hero Section management system has been fully upgraded. **No other page,
feature, route, or design element was modified.** All 51 pre-existing
backend tests still pass, and every other admin section and public page was
re-verified working after this change.

---

## What was tested

- **All 51 pre-existing backend tests pass** (`npm test`).
- **Live end-to-end test of the new Hero API**: draft save → live-preview
  fetch (unpublished, confirmed NOT visible on `/api/settings/public` until
  published) → publish → confirmed live → version history now stores a full
  33-field config snapshot per save → restore → media history log entries
  recorded correctly for every action.
- **Media uploads tested**: background video (desktop + mobile), background
  image (desktop + mobile), poster image, fallback image, and 3 slideshow
  images — each uploaded, listed, and deleted correctly, with old files
  removed from disk automatically on replace/delete.
- **Enable/disable toggle tested**: confirmed `hero_enabled=false` is
  reflected instantly in the public settings feed.
- **Unrelated features re-verified working**: Trainers, Products, and the
  health-check endpoint all responded correctly after every change.
- **Minified production assets rebuilt** via `frontend/build.js`.

## What was built

### 1–2. Background Media & Media Options
Upload/replace/delete for background video and image (desktop + mobile
variants), poster & fallback images, and a "Restore Default" path via
**Reset to Default**. Admin can switch the whole hero between **Video /
Image / Slideshow** backgrounds from one dropdown.

### 3. Slideshow Support
Up to 10 images, drag-to-reorder, auto-slide on/off, adjustable duration
(2–15s), and manual prev/next + dot navigation on the live site.

### 4. Hero Content
Main Heading, Sub Heading, Description, Join Now button (text + link),
Explore button (text + link) — all editable, all optional (blank keeps the
site's original copy).

### 5. Layout Controls
Text position (left/center/right), vertical alignment (top/center/bottom),
and a content-width slider (360–1000px), all live-previewable.

### 6. Video Controls
Autoplay, Mute, Loop, Lazy Loading, Quality Optimization, and Compress-on-
Upload toggles, plus Poster and Fallback image management. (Autoplay-off is
enforced end-to-end — the existing cinematic video-activation script was
given a small, surgical hook so it respects the setting rather than always
auto-playing.)

### 7. Overlay Controls
Enable/disable, opacity slider, color picker, and a gradient-vs-flat-color
toggle, rendered as a new overlay layer above the background.

### 8. Animation Controls
Text and button entrance animations can be toggled independently, with a
Slow/Normal/Fast speed control.

### 9. Mobile Optimization
Separate video and image uploads for mobile, applied automatically at the
≤820px breakpoint, plus a Desktop/Tablet/Mobile preview frame in the admin
panel.

### 10–11. Media Management & Safety
File size, upload date, and last-updated date shown per media file (read
live from disk). Delete confirmation popups on every destructive action. A
Media History Log lists every hero-related change with a timestamp. Uploads
reuse the site's existing format/size/corruption validation (magic-byte
checking, size limits, automatic image compression) — unsupported or
oversized files are rejected with a clear message, and uploads show a live
progress percentage.

### 12. Live Preview
A **Live Preview** button saves the current form as a draft and opens the
public site in a new tab with unpublished changes overlaid — visible only
in that preview tab, never to regular visitors — so the owner can check
everything before it goes live.

### 13. Publishing Controls
**Save Draft**, **Publish**, **Revert Changes**, and **Reset to Default**
— reset snapshots the current state first (so it's itself undoable) and
removes all uploaded hero media from disk.

## Files changed
- `backend/db/init.js` — new `hero_slideshow_images` table, expanded
  `hero_versions` table, ~30 new default settings.
- `backend/routes/settings.js` — Hero Section route block fully rewritten
  (draft/publish/revert/reset, media uploads/deletes, slideshow CRUD,
  media-info, history, versions).
- `frontend/admin/app.js` — `renderHeroAdmin()` rewritten with a card for
  every control group above.
- `frontend/index.html` — new background layers, overlay element, and
  content field IDs added to the existing Hero markup; new CSS added.
- `frontend/site-integration.js` — `loadHero()` rewritten to apply every
  new setting; slideshow rotation logic added.
- `frontend/premium/aurum.js` — two-line, backward-compatible hook so the
  existing cinematic video-activation logic respects the new Autoplay
  toggle (no other behavior changed).

Minified assets already rebuilt via `frontend/build.js` — re-run that any
time a source `.js`/`.css` file is edited again, before deploying.
