Review Comment:
   **🟠 Architect Review — HIGH**
   
   The updated renderHeader loop assigns numberColor on every formatter call 
without checking the return value, so when multiple conditional-format rules 
are configured, a later formatter that returns undefined will overwrite a 
previously matched color and clear the applied threshold color.
   
   **Suggestion:** Preserve the previous semantics by only updating numberColor 
when formatter.getColorFromValue(bigNumber) returns a truthy value, e.g. 
compute formatterResult inside the numeric-type check and guard the assignment, 
so that 0 still passes the numeric check but non-matching rules do not 
overwrite an earlier matched color.

   This is an **Architect / Logical Review** comment left during a code review. 
These reviews are first-class, important findings — not optional suggestions. 
Do NOT dismiss this as a 'big architectural change' just because the title says 
architect review; most of these can be resolved with a small, localized fix 
once the intent is understood.

   Validate the correctness of the flagged issue. If correct, How can I resolve 
this? If you propose a fix, implement it and please make it concise.
   If a suggested approach is provided above, use it as the authoritative 
instruction. If no explicit code suggestion is given, you MUST still draft and 
apply your own minimal, localized fix — do not punt back with 'no suggestion 
provided, review manually'. Keep the change as small as possible: add a guard 
clause, gate on a loading state, reorder an await, wrap in a conditional, etc. 
Do not refactor surrounding code or expand scope beyond the finding.
   Once fix is implemented, also check other comments on the same PR, and ask 
user if the user wants to fix the rest of the comments as well. if said yes, 
then fetch all the comments validate the correctness and implement a minimal fix
   ```
