arch page: alarms ride the node they watch, text fits its box, BYO boxes carry no price
Three defects found by rendering the page and reading the emitted SVG, none of which a test we had could see. Alarms were given the column between the IPs and the boxes — the only gap in the flow, and the one every IP-to-box edge crosses. Nodes paint after edges, so each alarm covered the line beneath it and the diagram read as a request reaching its box THROUGH an alarm. The modelling was wrong more than the placement: an alarm is not a hop, it is a property of the thing it watches. Each alarm is now a mark on its subject's node, coloured when firing (which also answers 'a firing alarm looks like a healthy one'), with its name and state in the node's hover title. TestNoNodeSitsOnAnEdgePath enforces the general invariant that was missing. Node text had no truncation at all, so a five-app list ran ~300 units across a 190-unit rect and bled over its neighbour. Text is now fitted to the box with an estimated glyph budget, and the full string survives as the node's hover title. A bring-your-own box showed $17/mo from the default rate-card spec. The rate card prices what this platform pays for; a Pi on someone's desk is not that, so the figure was a claim about someone else's bill. Such a box is now unpriced, and keeps only the plain statement that it has no cloud machine. Spec §6.2 and §6.4 amended to describe what ships.
