Rack Rendering Model

Chunk 14 introduces the first reusable rack elevation model for InfraLynx.

Core Rules

• rack devices are positioned by explicit starting U and height
• rendering order is deterministic from highest U to lowest U
• rack occupancy is derived from reusable slot generation helpers
• device blocks span multiple units visually without duplicating device metadata

Ownership

• API payloads provide rack, device, port, and cable data
• @infralynx/ui owns slot generation and rack geometry helpers
• apps/web owns the React rendering and selection behavior

Visual Model

• each rack unit is rendered as a grid row
• devices visually occupy all units they span
• the starting unit renders the main device label and metadata
• continuation units preserve occupancy without repeating the full label block

Cable Model

Cable visualization is intentionally lightweight in this chunk.

• ports expose peer labels and cable IDs
• the selected port renders a simple source-to-destination cable trace
• full topology visualization remains a later chunk
