I run a small HTML / CSS / JavaScript site-builder that lives on Heroku. The next sprint is all about tidying up the look and locking down the bits that shouldn’t be public. Here’s what I need tackled: • Securely move my Extractor API key and the RSS2JSON feed key out of the codebase and into Heroku config vars (or an equivalent approach) so nothing sensitive ever ships to the browser. • Wire the Extractor feed into the reader-text cleaner in a way that guarantees the automatic highlighting routine never misses. Smooth, predictable data flow is the goal. • Unify the visual language across the entire app—consistent fonts and colours, perfectly aligned headers and footers, and the same style for every button, form field, link and bit of copy. • Make sure any sub-apps I’ve bolted on work together seamlessly within the main flow. Everything is already deployed on Heroku, so familiarity with its config, buildpacks and pipelines will help you move fast. Once the config changes are live and the styling passes review in modern browsers, we’re done.
