Live test preview: https://smithright.github.io/smithright-tools/presentation-template/

Adds presentation-template/ with Fold, a portable presentation that keeps the main idea on a 16:9 canvas and supporting detail below it. The generated HTML opens directly from disk or a hosted subfolder and includes a local editor with drag/keyboard reordering, undo/redo, JSON import/export, and standalone HTML download.

Seven original SVG and typography examples cover editorial geometry, technical blueprints, animated feedback systems, isometric scenes, cinematic game-studio atmosphere, data comparison, and expressive typography. All assets are inline; the default presentation makes no external requests.

The source contract uses versioned JSON and stable slide IDs. The build is dependency-free. Documentation covers agent authoring, GitHub Pages, local drafts versus published state, licensing, and the two PDF modes.

Validation on Chrome 154:

• Rebuilt the committed HTML; strict model validation and malformed-input controls passed.
• Opened offline, navigated all seven slides, entered/exited fullscreen, and used reading/overview modes.
• Edited and reordered through the rendered UI; exported and reopened HTML with content and order intact.
• Verified JSON import, undo/redo, browser draft restoration, and storage-disabled download recovery.
• Checked all seven desktop canvases and mobile-sized layouts for clipping/overflow.
• Generated and visually inspected PDF output: 7 pages for slides, 14 with details.
• Tested HTTP hosting under a subfolder; no page errors or external requests.

A scoped CI workflow repeats the browser checks and retains screenshots/PDF evidence. Safari, Firefox, physical mobile devices, and touch dragging remain unqualified; reorder buttons provide a drag-free alternative. Browser edits are local drafts until downloaded and explicitly published.

The gh-pages preview is deployed separately from this unmerged PR. Public HTTP readback matches the built HTML by SHA-256, and a live edit/reorder/download/reopen-offline check passed.
