post.html: gear-btn + #id_post_menu (NVM / DEL / BYE) mirror room.html's #id_room_menu — all Posts get the gear w. NVM (→ billboard:my_posts); user-Posts (kind=USER_POST / SHARE_INVITE) additionally surface DEL for the author (POST → billboard:delete_post → hard-deletes the Post; cascades Lines via FK + clears shared_with M2M) and BYE for invitees (POST → billboard:abandon_post → removes request.user from post.shared_with; owner + other invitees keep the thread); admin-Posts (kind=NOTE_UNLOCK) intentionally render gear w. NVM only since the system thread isn't user-owned (defence-in-depth: both delete_post + abandon_post no-op on NOTE_UNLOCK so a forged POST can't bypass the menu's branch); _post_gear.html partial gates DEL/BYE on viewer_is_owner (set by view_post since the buds sprint) + post.kind, then includes the shared apps/applets/_partials/_gear.html btn; styling rides the existing applets.scss page-level pattern — .post-page joins .billboard-page / .room-page / .dashboard-page / .wallet-page / .gameboard-page / .billscroll-page in the > .gear-btn { position: fixed; bottom: 4.2rem; right: 0.5rem } rule (and the landscape footer-sidebar centred variant), #id_post_menu joins the %applet-menu extension list + the page-level fixed-menu rule (bottom: 6.6rem; right: 1rem); 5 FTs in test_bill_post_gear.py (owner DEL flow, invitee BYE flow, 3 menu-shape assertions for owner/invitee/admin) + 11 ITs across DeletePostViewTest + AbandonPostViewTest (302 redirect target, side effect, GET-is-no-op, non-owner / non-invitee / NOTE_UNLOCK protection) — TDD
