+# HORRIBLE HACK BUT WORKS :-) PR anyone?

+# Why?
+# `browsersteps_playwright_browser_interface.chromium.connect_over_cdp()` will only run once without async()
+# - this flask app is not async()
+# - browserless has a single timeout/keepalive which applies to the session made at .connect_over_cdp()
+#
+# So it means that we must unfortunately for now just keep a single timer since .connect_over_cdp() was run
+# and know when that reaches timeout/keepalive :( when that time is up, restart the connection and tell the user
+# that their time is up, insert another coin. (reload)
+#
+# Bigger picture
+# - It's horrible that we have this click+wait deal, some nice socket.io solution using something similar
+# to what the browserless debug UI already gives us would be smarter..
+#
+# OR
+# - Some API call that should be hacked into browserless or playwright that we can "/api/bump-keepalive/{session_id}/60"
+# So we can tell it that we need more time (run this on each action)
+#
+# OR
+# - use multiprocessing to bump this over to its own process and add some transport layer (queue/pipes)

+# Change detection post-processors
+
+The concept here is to be able to switch between different domain specific problems to solve.
+
+- `text_json_diff` The traditional text and JSON comparison handler
+- `restock_diff` Only cares about detecting if a product looks like it has some text that suggests that it's out of stock, otherwise assumes that it's in stock.
+
+Some suggestions for the future
+
+- `graphical` 
+- `restock_and_price` - extract price AND stock text
