Challenge: Auditing an Inconsistent Icon Set

Review this real-world icon set audit from a fintech application:

• Icon 1 (Search): 24 $\times$ 24px bounding box, 2px stroke, round caps.
• Icon 2 (Bell): 18 $\times$ 22px rectangular box, 1px stroke, square caps.
• Icon 3 (Settings): 32 $\times$ 32px box, solid black fill.
• Icon 4 (User): Hardcoded #333333 fill with no currentColor support.

Systemic Normalization Plan:

1. Place all icons into identical 24 $\times$ 24px square viewports.
2. Standardize all resting strokes to 2px rounded stroke.
3. Remove hardcoded fills and apply stroke="currentColor" fill="none".
4. Apply optical weight compensation keylines so the Bell and Search icons have equal visual presence.
