Self-host HOA docs, refresh tagline, clean welcome photo, fix contact

- Homeowner Information: download the six HOA PDFs from pinecreekhoa.com into
  /docs and repoint the document cards to the local files (self-contained;
  no cross-site dependency).
- Hero tagline: "A premier gated community of custom luxury homes" ->
  "Cabarrus County's premier gated community of custom estates".
- Welcome photo: digitally clean the stained concrete driveway and paver
  apron in IMG_1964 (hue-masked desaturate/lighten/even-out via ffmpeg;
  grass, brick, and sky untouched).
- Contact: "Email the HOA" button now uses president@pinecreekhoa.com.

 # Homeowner Documents
 
-The Homeowner Information section of `index.html` currently links to the live
-PDFs hosted on **pinecreekhoa.com** (they could not be downloaded automatically
-because that site sits behind a browser-isolation proxy, but they open fine in a
-normal browser).
+These PDFs are self-hosted and linked from the Homeowner Information section of
+`index.html`. They were copied from the production site (pinecreekhoa.com).
 
-When this site takes over the `pinecreekhoa.com` domain, make the documents
-self-hosted so the links keep working:
+| File | Document |
+|------|----------|
+| `PineCreekCCR.pdf` | Pine Creek Neighborhood Covenants |
+| `vineyardccr.pdf` | The Vineyard Supplemental Covenants |
+| `Pine-Creek-Safety-Rules.pdf` | Safety Rules & Regulations |
+| `HOAApprovalForm.pdf` | Architectural Review Approval Form |
+| `Pine-Creek-Delinquency-Policy.pdf` | Delinquency Policy |
+| `Pine-Creek-Request-for-Reimbursement-of-Costs-for-Community-Event.pdf` | Community Event Reimbursement Form |
 
-1. Save these six PDFs from the current site into this `docs/` folder:
-   - `PineCreekCCR.pdf` — Pine Creek Neighborhood Covenants
-   - `vineyardccr.pdf` — The Vineyard Supplemental Covenants
-   - `Pine-Creek-Safety-Rules.pdf` — Safety Rules & Regulations
-   - `HOAApprovalForm.pdf` — Architectural Review Approval Form
-   - `Pine Creek Delinquency Policy.pdf` — Delinquency Policy
-   - `Pine-Creek-Request-for-Reimbursement-of-Costs-for-Community-Event.pdf` — Community Event Reimbursement Form
-2. In `index.html`, change each `.doc-card` `href` from
-   `https://www.pinecreekhoa.com/<file>` to `docs/<file>`.
+To update a document, replace the file here (keep the same name) or update both
+the file and its `href` in the `.doc-grid` of `index.html`.
