+# Power Profile Management
+
+## Purpose
+
+This capability provides configurable power management profiles that control system behavior such as screen blanking, locking, and suspension.
+
+## ADDED Requirements
+
+### Requirement: Manage Power Profiles
+The system SHALL provide three distinct power management profiles: `caffeinated`, `headless`, and `normal`.
+
+#### Scenario: Caffeinated Profile
+- **WHEN** the `caffeinated` profile is active
+- **THEN** the system SHALL NOT blank the screen.
+- **AND** the system SHALL NOT lock the screen.
+- **AND** the system SHALL NOT suspend.
+
+#### Scenario: Headless Profile
+- **WHEN** the `headless` profile is active
+- **THEN** the system SHALL blank the screen after a timeout.
+- **AND** the system SHALL lock the screen when it blanks.
+- **AND** the system SHALL NOT suspend.
+
+#### Scenario: Normal Profile
+- **WHEN** the `normal` profile is active
+- **THEN** the system SHALL blank the screen after a default timeout.
+- **AND** the system SHALL lock the screen when it blanks.
+- **AND** the system SHALL suspend after a longer default timeout.
+
+### Requirement: Cycle Through Power Profiles
+The system SHALL allow the user to cycle through the power profiles using a keybinding.
+
+#### Scenario: Cycle Forward
+- **WHEN** the user presses the "next profile" keybinding
+- **THEN** the active power profile SHALL change from `normal` to `caffeinated`, `caffeinated` to `headless`, and `headless` to `normal`.
+
+#### Scenario: Cycle Backward
+- **WHEN** the user presses the "previous profile" keybinding
+- **THEN** the active power profile SHALL change from `normal` to `headless`, `headless` to `caffeinated`, and `caffeinated` to `normal`.
+
+### Requirement: Visual Indicator for Current Profile
+The system SHALL display the current power profile mode in the Waybar status bar.
+
+#### Scenario: Display Caffeinated Icon
+- **WHEN** the `caffeinated` profile is active
+- **THEN** a "caffeinated" icon SHALL be visible in the Waybar status bar.
+
+#### Scenario: Display Headless Icon
+- **WHEN** the `headless` profile is active
+- **THEN** a "headless" icon SHALL be visible in the Waybar status bar.
+
+#### Scenario: Display Normal Icon
+- **WHEN** the `normal` profile is active
+- **THEN** a "normal" icon SHALL be visible in the Waybar status bar.
