Literally only using either Notepad++/FileZilla on desktop or an iOS FTP text editor combined with iOS Shortcuts if on mobile to generate and apply new posts.
For Notepad++ I saved macros for different post formats, the macro pulls the URL from my clipboard and wraps it in the HTML according to which shortcut key.
The iOS workflow does the same thing and lives as a cluster of app icons that trigger custom iOS Shortcuts in a folder on my Home screen, I just tap it, it pops-up an iOS input modal asking for the post title, then automatically wraps the HTML around both the text I input as well as the URL I already copied onto my clipboard, then takes the entire HTML chunk and overwrites my clipboard with it so I can paste into the index.html via the iOS FTP text editor.
In both cases it’s simple and fast, on iOS the FTP editor is always editing the live file, on desktop I just download the latest using FileZilla prior to doing any edit/upload. When on desktop I also (when not in a hurry) commit the latest version to a git repo.
(For larger and less commonly used updates, like formatted sections or special link highlights, I just have a templates.html file that I copy from as needed.)
