LET'S PLAY THE GAME

The Phantom Five await your click,
Scattered across the digital brick.
Invisible to eyes untrained,
But to the curious, they're unchained.
Where console logs reveal the truth,
And elements hide their proof.
Some nested deep in layers of DOM,
Others masked by transform.

Five fragments of the final key,
Not all that renders can you see.
Inspect the source, query the nodes,
the answers lie within the codes.

Accumulate the hidden score,
To unlock the challenge door.
Only those who parse the page,
Are worthy of the final stage.
