Increase strip density and board fill across anchor modes

[joryirving]

Summary

Increase the number of tiles and improve how the board fills the available strip area.

Current State

• Anchor-specific board dimensions exist
• Tile size is now computed relative to dock size
• The strip is denser than before, but still not dense enough on some displays

Problems Observed

• There are still not enough tiles for the available space, especially on large monitors
• The board can still occupy only a corner-like portion of the dock
• Empty margins and underused space still break the desktop-strip fantasy

Desired Behavior

• The colony should feel like a dense, living strip of simulation
• Board density should scale sensibly with monitor size and anchor family
• Tiles should make strong use of the available strip space without becoming illegible

Implementation Notes

• Increase tile counts per anchor family beyond the current baseline where appropriate
• Tune tile-size scaling logic against real dock width/height ratios
• Revisit strip padding and board margins
• Prefer a world that visibly fills the dock over one with generous breathing room
• Keep the board readable at a glance; density should not turn into noise

Acceptance Criteria

• The strip contains noticeably more world state
• Tiles scale to make good use of available dock space
• Empty dead areas are reduced in both bottom and vertical modes
• The world remains readable at a glance
