The day after posting this request for help, the DRC error simply disappeared when opening up my project just now.  I wouldn't have been able to offer a meaningful screen shot because no visual indication of errors ("X") appeared anywhere on my PCB design.  This was the case when I posted, the only DRC "error" being the two "Net Pin" errors of which no visible error indication was present at the two pins in question. Thank you Andy for your constant vigilance in offering help within hours. I haven't seen any notation on how to help support EasyEDA, and I'd like to help.
