Choose a download you can use.
Before paying
Try the free example and read the exact paid contents and limitations. Check the required runtime or editor. Free alternatives are described on relevant product pages. The paid benefit is the original prepared workflow, source, exercises or explanations.
Files and starting instructions
Packages are ZIP archives. Download and extract the whole ZIP into a local folder, then read README or START-HERE before opening individual files. Keep the folder structure intact. Browser module tools need localhost or HTTPS; double-clicking an HTML file is not supported unless its instructions say so. Node-based runners and React starters have their own stated requirements.
Source and format compatibility
Editable source does not promise compatibility with every editor or software version. Diagram SVGs are verified for browser display and supplied source regeneration. The casebook PDF was visually checked; native EPUB/Kindle compatibility is not established. The rehearsal deck was visually checked and a private Google Slides import/edit/export round-trip was verified. Native Office compatibility remains unverified. SavePatch is retired from this launch; its native-editor workflow was never verified.
Usage rights
Read the license supplied with the chosen package. A purchase does not transfer copyright or automatically permit redistribution, resale or a marketplace reupload. Third-party and separately licensed free components retain their own notices.
Checkout and delivery
The fifteen standalone products are available through Payhip at their listed USD prices. The two bundles remain closed. Payhip supplies the receipt and download link after a completed purchase. Keep your receipt and ZIP backup. The free proofs remain available without purchase. PayPal currently supports international buyers for this store; final taxes and payment availability are shown at checkout.
If a file is missing or an example fails
Use the seller contact form or the contact route in your purchase receipt. Identify the product/version, filename, operating system, runtime and error. Use a small synthetic example; do not send passwords, bank details, real customer records or private inputs. Custom implementation, guaranteed response times and indefinite future updates are not included.
Payment and delivery information
Check the final checkout for currency, applicable taxes and payment availability. Read the seller delivery, support and usage policy. Report missing/corrupt delivery or a material mismatch for review and correction. Applicable consumer rights and provider rules remain in effect.
