a coworker recognized my hand tattoo from a public insta i did a takeover on for a lifestyle event

so im stupid. short version : a friends couple runs a lifestyle event series and i did an instagram takeover (story takeover, on their public ish account) for them 3 weeks ago. promoting their next event. i was very careful — sunglasses, no full face, voice modulated in the talking bit. felt safe. except one of the b-roll clips was me holding a drink and the camera caught my left hand for like 2 seconds. and my left hand has a very specific tattoo. a piece my late dad designed, one of a kind, ive had it 12 years. today at work a coworker said in passing "hey i saw your hand on [event accounts] story last week, cool tattoo". just like that. casual. like she was complimenting it. then she walked away to a meeting. i sat at my desk and felt my face go cold. i have NO IDEA how she knows that account. she is not someone i would have ever guessed is lifestyle adjacent. low key religious-y, kid in 2nd grade, married, the type who brings homemade muffins for the team birthday thing. but she clearly follows that account or saw it shared somehow. she didnt say anything else. didnt act weird. didnt do a wink. just complimented the tattoo and went to her meeting. what i cant figure out is whether to bring it up or let it sit. f36, single, lifestyle 4 yrs, work in marketing at a mid sized firm. industry is small ish. she is not in my direct chain but we share a department. my partner (we have been dating 8 months, hes also lifestyle) says do absolutely nothing. dont confirm, dont deny, dont reference it, "if she wanted to use it against you she wouldnt have warned you, that comment was almost certainly a "i see you and im not a threat" signal". but my partner is way calmer than me about everything. the part im stuck on is — she now knows. so what i do with that going forward at work matters. do i act normal. do i become slightly warmer to her to build a vague unspoken truce. do i avoid her bc thats suspicious. is there any version where i should preemptively address it (like later this week over coffee, low key). oh and btw, i told the event couple. they felt awful. theyre offering to take the takeover down which doesnt undo the damage but the thought counts. i told them keep it up, its been 3 wks, taking it down NOW would only confirm my situation if anyone else is watching.
