Primary Bath Refresh

What changed

• New field: On every project, the Project Details box now has a “Project description” rich text box under the short summary. It has the usual formatting toolbar, and its help text suggests short paragraphs and subheadings.
• Single template: The description appears between the header and the photo gallery, styled to match the site (Source Sans body text, Manrope headings, navy links).
• Removed from the template: I removed the Post Content widget and the excerpt paragraph. That stops the old stored layouts from ever coming back, and it avoids the excerpt repeating right next to the description.
• Kept: The excerpt still feeds the archive cards, and the short summary still shows in the header.
