The Placeholder content class — a decorative spacer button used to balance grid layouts or reserve a slot for future content.

The Home (tab bar) content class — the home-screen shortcut placed in the bottom tab bar. Distinct from the Home Screen Stack itself; this is the navigation entry to it.

The Punch Out content class — punch-in / punch-out button for time tracking. Backed by mam_punchin_handler in helper-classes; supports geofencing and shift configuration.

The Settings Menu content class — opens the user’s settings drawer (profile, notification preferences, log out, app version). Sibling plugins extend the menu via mam_main_content_class_settings.

The Onboarding content class — first-launch carousel of intro screens shown to new users. Configurable per-slide content, CTA, and a returning-user toggle.
