Pixel field

A grid of heat cells behind your content. The pointer writes into it, time decays it, thresholds turn it into colour. The same grid carries every behaviour: charge and detonate, a pixel-text scroller, an arrow that points at tagged headings, glyph stamps inside tagged zones, and a small creature that wanders in when you stop moving. Tag targets with data-pixel-arrow and data-pixel-shape.

One grid, five moods

Heat, held and released.

Heart zone The trail snaps into a two-scale pixel heart in here, with a spark burst on entry.

Star zone Same stamp, different glyph. Any key of PixelField.glyphs works.

Move — paint heat into the grid.
Hold, then release — charge a blob and detonate it (charge presets).
Double-click — instant shockwave.
Stop moving — the creature preset sends a wanderer across the field.
Panel — every slider writes straight to the live engine. H hides it.
