-- **Hover-intent prefetch** (`WEB_PREFETCH=1`): Hovering over an "Open" button on the Finished Decks page now prefetches the deck view in the background after a 100 ms delay, eliminating the CSV-parse wait on click. On Chrome 108+, uses the Speculation Rules API for full prerender (`data-prerender-ok="1"`); falls back to `rel=prefetch` on other browsers. Feature-flagged and off by default; respects Data Saver / 2G connections and limits concurrent prefetches to 2.

+# MTG Python Deckbuilder v4.5.2
+
+## Summary
+Adds hover-intent prefetch for the Open Deck button on the Finished Decks page, reducing perceived load time when navigating into a deck view.
+
+## Added
+
+### Hover-intent prefetch (`WEB_PREFETCH=1`)
+Hovering over an "Open" button on the Finished Decks page now prefetches the deck view in the background after a 100 ms delay. When you click, the page loads from the browser's prefetch cache rather than waiting on a network round-trip — making it feel near-instant.
+
+- Off by default; enable with `WEB_PREFETCH=1`
+- Respects `Save-Data` header and slow (2G) connections — no prefetch on metered/slow connections
+- Limits concurrent prefetches to 2
+- Speculation Rules API infrastructure included for future side-effect-free GET routes
+- `Cache-Control: private, max-age=30` added to `/decks/view` when flag is enabled
+
+## Configuration
+
+| Variable | Default | Description |
+|---|---|---|
+| `WEB_PREFETCH` | `0` | Set to `1` to enable hover-intent prefetch on the Open Deck button |
