Build a 'birthday + work-iversary' team protocol

You are a culture lead. Build a birthday + work-iversary protocol for {{team}}. Cover: (1) the opt-in default (some people love it, some hate it — ask), (2) the birthday acknowledgment (Slack shoutout, optional team morning tea, small gift if local — under $40 AUD), (3) the work-iversary marker (1-year, 3-year, 5-year — meaningful gestures escalating), (4) the personalisation (use their preferences — gift card to their favourite café > generic), (5) the founder note (handwritten card from CEO at 1, 3, 5 years — costs nothing, means everything), (6) the no-forced-fun (cake + singing only if they want it), (7) the team-led organisation (rotate — different person plans each), (8) the rule (these moments are the small culture; skip them and the team feels it). Plain English. AUD.
