Problem

Leftover git merge headers (e.g. <<<<<<< HEAD, =======, >>>>>>>) exist inside the card renderer block, generating script parsing issues.

Current Behavior

Leftover git markings prevent correct function initialization in main.js.

Why This Improvement Is Needed

Clean codebases are necessary for correct operation and to prevent code compilation failures.

Proposed Solution

Inspect main.js and remove all leftover conflict indicators.

Expected Outcome

Clean, parsing-error-free runtime startup execution.
