inteligir Canvas

Canvas is a rough spatial surface: boxes, connectors, and relative position. It is not a diagram renderer and not a place for readable sentences.

When To Reach For It

Use canvas when someone asks for a canvas, edits an existing one, or wants a sketch they can rearrange. Use a plaintext code fence for a generic flow, wireframe, or menu sketch — ASCII stays readable everywhere, including in a diff. Use a chart for quantity and an image for anything polished.

The test: if the words matter more than where the boxes sit, canvas is the wrong block.

The Payload

```inteligir-canvas
[inteligir:grid:v2]
[inteligir:labels:[{"id":"draft","text":"Draft","col":8,"row":4}]]
....########................
....#......#................
....########................
```

In order: the grid marker, an optional single-line labels array, then grid rows.

The grid is 120 columns by 60 rows. Missing cells pad empty, extra cells truncate, and a saved canvas normalizes to the full size.

Every character except . and space becomes ink. Letters do not stay readable — an A is a smudge, not a letter. All readable text goes in labels.

Labels are objects with:

Field	Contract
id	Unique within this canvas, non-empty
text	Non-empty, keep under 80 characters
col	Integer, 0–119
row	Integer, 0–59

The labels line must be valid compact JSON on one line.

Drawing Something Readable

• Count columns deliberately, or generate the rows programmatically. Hand-aligned ASCII drifts by one character and the whole sketch skews.
• Favor rectangles, straight connectors, and generous space.
• Do not draw arrowheads out of < and >; show direction with layout and labels.
• Keep strokes clear of where labels sit.
• If you cannot verify the result renders, simplify it or use an ASCII fence instead. A wrong canvas is harder to fix than a plain diagram.

Before You Finish

• The block was asked for, not substituted for a diagram.
• The grid marker and labels JSON are valid and correctly ordered.
• Every coordinate is inside 120×60 and every label id is unique.
• No readable text is hiding in the grid.
