+### Play Online Logic Implementation
+
+**Status**: Completed
+**Date**: 2025-12-17
+
+**Description**
+Implemented pack count validation logic for "Play Online" to strictly enforce draft player limits.
+
+**Changes**
+1.  **Rule Enforcement**:
+    -   **< 12 packs**: Button visual disabled (slate color), shows error toast explaining rules if clicked.
+    -   **12-17 packs**: Allows entry, shows toast "Enough for 4 players only" (Info).
+    -   **18-23 packs**: Allows entry, shows toast "Enough for 4 or 6 players" (Info).
+    -   **24+ packs**: Allows entry, shows toast "Enough for 8 players!" (Success).
+2.  **UI Feedback**: Updated button class logic to visually reflect availability based on pack count.
+
+**Effect**
+Prevents users from starting unplayable drafts and informs them of the capacity their current pool supports.

+
+### Lobby Rules Tooltip
+
+**Status**: Completed
+**Date**: 2025-12-17
+
+**Description**
+Added a dynamic tooltip and status indicator to the Online Lobby to explain draft capacity rules based on pack count.
+
+**Changes**
+1.  **Info Icon**: Added an `AlertCircle` icon with a hoverable tooltip explaining the pack requirements (3 packs/player).
+2.  **Dynamic Rules**: The list of rules highlights the currently applicable tier based on pack count (e.g., turning green for "12-17 Packs" if 15 packs are available).
+3.  **Status Line**: A summary line explicitly states "Supported Players: [Status]" under the pack count.
+
+**Effect**
+Users can now clearly see why they might need more packs before creating a room, and what player counts are supported with their current pool.
