This is a Stencil-based web component intended to support the submission of comments to an otherwise static blog implemented with Hugo.
The web component is embedded into a special Contact page, that is opened in a separate frame whenever a comment on the blog post is requested. Which post or which comment the new comment replies to, that is indicated by the URL fragment of the Contact page.
As the requesting blog lacks a proper backend (it's static after all), the comments are submitted to an Amazon Simple Queue Service (SQS) message queue.
