Minor fix. Perhaps after 'define ' Kagi could internally convert letters to lowercase 🤔.
This is quite silly. If I search for "define Spectacular" or "define SPECTACULAR" or "define spectaculaR", the Dictionary widget does not load. I must search "define spectacular".

This is a nag, because, we have gotten used to search returning quality results irrespective of letter case. It is very common we copy words from text (which may have non-lowercase letters) to see their definition. Sometimes, these words are in ALL CAPS (eg: legal disclaimers). Sometimes also, the user is haste and ends up with mixed case. But again, when I say 'define ' I expect a definition, irrespective of letter case, plural vs singular form, incorrect spelling, etc.
