Restores the 208 catalog items reverted after their previews 404'd in production, this time on the payload mechanism rather than the .html files that caused the outage. The generator no longer writes a preview document to docs/public. That writer, and the machinery under it, existed only to produce files the docs host discards, so it is gone rather than bypassed. Items now embed the composition itself via a payload, which is what the previous change already does for the items that were already in the catalog. The variables explorer is parked, not restored: it drove its preview through the same unpublished .html path, so it would have shown an empty frame. Items that declare variables get the live player plus the static variables table, and reconnecting the explorer to payloads is a follow-up.

## Install
|
|
|
|
<InstallCommand command="npx hyperframes add dynamic-grid" />
|
|
|
|
That writes one file: `compositions/components/dynamic-grid.html`.
|
|
|
|
## Variables
|
|
|
|
Every one of these has a default, so the piece works untouched. Set the ones you
|
|
want to change on the element:
|
|
|
|
| Variable | Default | Accepts | What it does |
|
|
| --- | --- | --- | --- |
|
|
| `density` | `standard` | `fine`, `standard`, `coarse` | Cell size of the grid: fine reads as graph paper, coarse as a few large panels. |
|
|
| `weight` | `hairline` | `hairline`, `standard`, `bold` | Thickness of the grid lines, from a hairline rule to a bold structural grid. |
|
|
| `tone` | `neutral` | `neutral`, `green`, `blue`, `violet` | Line colour: neutral is the translucent white the original ships with, and the accents ride --brand, --accent and --accent-2. |
|
|
|
|
Set them with `data-variable-values` on the element that mounts it. These are the
|
|
defaults, so this behaves exactly like the preview above until you change one:
|
|
|
|
```html wrap
|
|
<div
|
|
data-composition-id="dynamic-grid"
|
|
data-composition-src="compositions/components/dynamic-grid.html"
|
|
data-variable-values='{"density":"standard","weight":"hairline","tone":"neutral"}'
|
|
></div>
|
|
```
|
|
|

Dynamic Grid - animated background primitive.
|
|
|
|
Paste the grid as the first child of a scene. Animate --hf-grid-x,
|
|
--hf-grid-y, and --hf-grid-opacity from your paused GSAP timeline.
|
|
|
|
Variables. The script reads each one, falls back to the declared default on
|
|
anything missing or unrecognised, and writes the result as a custom property
|
|
the CSS consumes. The timeline recipe below is untouched by them: it keeps
|
|
driving the scroll offset and the opacity.
|
|
|
|
- density (fine | standard | coarse, default standard): cell size of the
|
|
grid, 44px, 72px or 112px. fine reads as graph paper, coarse as a few
|
|
large panels.
|
|
- weight (hairline | standard | bold, default hairline): line thickness,
|
|
1px, 2px or 3px.
|
|
- tone (neutral | green | blue | violet, default neutral): line colour.
|
|
neutral is the translucent white the original ships with, and the three
|
|
accents ride --brand, --accent and --accent-2.
|
|
|
|
On every default the result is identical to the original: 72px cells drawn
|
|
in 1px translucent white lines.
