Summary of Issue: Adding \"at least\" to second sentances of 1.4.3 & 1.4.5
Comment (Including rationale for any proposed change):
I think we meant to say large-scale text or image of text has <new> at least </new> a contrast ratio of 3:1 (1.4.3) or 5:1 (1.4.5).

Proposed Change:
1.4.3 Text (and images of text) have a contrast ratio of at least 5:1, except if the text is pure decoration. Larger-scale text or images of text can have a contrast ratio of at least 3:1.



1.4.5 Text (and images of text) have a contrast ratio of at least 7:1, except if the text is pure decoration. Larger-scale text or images of text can have a contrast ratio of at least 5:1.
