Spec Delta
Purpose
Defines how the arena default size is derived from the output and how resizing affects the grid.
ADDED Requirements
Requirement: Default arena is about 80% of output
The system SHALL compute the default logical window size as 80% of the output mode dimensions divided by the active scale.
Scenario: Output available
- WHEN output mode and scale are known at startup
- THEN the default logical window size is approximately 80% of the output
Requirement: Fallback when output unknown
The system SHALL use a fallback default size when output info is unavailable.
Scenario: No output info
- WHEN output mode is not reported
- THEN a fallback logical size is used
Requirement: Cell size remains 8 logical pixels
The system SHALL keep an 8 logical pixel cell size.
Scenario: Grid dimensions
- WHEN the logical window size is known
- THEN grid columns and rows are logical size divided by 8
Requirement: Resizable window
The system SHALL allow the window to be resized by the user.
Scenario: Resize
- WHEN the user resizes the window
- THEN the grid dimensions update accordingly
Requirement: Grid preserved on resize
The system SHALL preserve overlapping cells when the grid dimensions change.
Scenario: Enlarge
- WHEN the window grows
- THEN existing cells within the old bounds remain
