Prepare a campaign link
Build consistent source, medium and campaign fields, then inspect the query pairs. Preserve destination parameters and avoid modifying signed URLs without testing them.

Decode escaped text
Choose the representation first: percent escapes, Base64 bytes and HTML entities are different layers. Decode once and inspect the plain-text result before another transformation.
Check color contrast
Use the foreground and background at their actual size and weight. A rounded ratio can hide a failing threshold; read the explicit AA/AAA result.
