A cleaner left-hand navigation

The left sidebar was carrying too much at once, so we gave it clearer edges. The live trading desk is now flat: the chart, option chain, positions, and activity views sit side by side, each a single click away, instead of nested behind a menu.

Practice and Replay each moved into a section of their own. Practice is where you trade a past session forward from the open; Replay is where you step back through a day you've already settled. Keeping them apart means the controls for the one you're using are right there, without the other's getting in the way.

While we were in Replay, playback also gained a speed control — pick how fast the session runs so you can skim the quiet stretches and slow down where it matters.
