The transaction detail's Identity row now carries a small two-tone gradient dot in that identity's OWN gradient, drawn with the exact identicon math (gradient_rgb8, refactored out of gradient_params so the dot matches the identity's avatar everywhere). The dot is theme-aware and deliberately quiet: a faint fill plus a faint ring that stays legible on both light and dark backgrounds without becoming a bright chip. A per-row cue in the activity list is intentionally OFF (SHOW_ROW_IDENTITY_CUE = false): on a row the avatar is the counterparty, so a gradient dot there is both redundant with that avatar and does not tell the user which of their OWN identities was used. The plumbing (the seam const, a per-frame identity context, ActivityItem.owner_pubkey recording the tx's owning identity) is kept so a proper own-identity cue can be added later in one place, but it renders nothing now. The switcher page and profile card already show the active identity via its own gradient avatar and name.
