Timeline Button: Fix Mobile Double-Toggle

Output

🌌 Timeline Button Fix (Commit a42d2fb5)

Root Cause Found

The button had both an inline onclick attribute AND JavaScript event listeners. On mobile:

touchend fires → toggles panel OPEN
e.preventDefault() blocks synthetic click
But onclick attribute is NOT blocked by preventDefault!
onclick fires → toggles panel CLOSED
Result: Nothing appears to happen (instant open+close)

Fix Applied

Before:
<button onclick="...toggleFlowTimeline()...">

After:
<button id="nav-timeline-btn">
// Handlers bound ONLY via addEventListener in JS

Additional Improvements

Added retry mechanism (5 attempts, 100ms apart) if button not found
Split handler binding into separate function for clarity
Better logging for debugging

Test on Samsung Fold 7

Open console logs (Chrome remote debug or Eruda) and verify:

[Timeline] Binding button handlers
[Timeline] Button handlers bound successfully
[Timeline] Button touchstart
[Timeline] Button interaction: touchend target: nav-timeline-btn

If you see this but panel still doesn't open, there's something else blocking.
