- Pull the item list down from its top: checks the feed (or every feed, on All Subscriptions) for new items, which arrive as they do from the scan button. overscroll-behavior keeps the browser's own pull-to-reload out of it. - Swipe the item you are reading left for the next, right for the one before, or back to the list from the first. A vertical move is a scroll; something that scrolls sideways, or takes typing, keeps its own swipe. Touch events only, so a mouse never sets them off. Closes #22.

// Builds the pages ipx serves: each page's TypeScript from web/src, types stripped and minified
|
|
// by swc into a script of its own (app.js, login.js), and the page minified, its
|
|
// <script data-src> pointing at that script. build.rs runs it into OUT_DIR, where web.rs
|
|
// include_str!s the results, so the binary still carries everything and nothing is served
|
|
// from disk.
|
|
//
|
|
// The page names its script with a hash of the script's contents, /app.js?v=<hash>, and the
|
|
// server lets a browser keep that for a year without asking again. A changed script is a new
|
|
// URL, and the page, which the browser checks on every visit, is what carries it.
