Heat Damage to Laminate Counter-top Near Gas Range
There appears to be insufficient gap and the range appears to be too low. The easiest thing would be to raise the range by 3/4 inch to 1 inch. This might reduce heating of those areas.
EDIT
Might benefit from a stainless steel gap cover like this https://www.amazon.com/Stainless-Steel-Counter-SILICONE-splatter/dp/B089B6G3XZ
Current gap covers appears to be guiding flame onto counter.
