The generated catalog pages rendered the "Source" accordion title as a
JSX expression, `<Accordion title={`name.html`}>`. Mintlify's search
indexer stringifies expression attribute nodes rather than evaluating
them, so every one of the 399 catalog pages surfaced its Source section
in search results as "[object Object]" (visible on the Scroll Feed page,
among others).
The template literal carried no escaping benefit: every title is a
single-segment `name.html` path, and a double-quoted JSX string handles
it directly. Introduce `mdxStringAttribute`, which emits a plain
`name="value"` attribute and escapes `& " < { }` as HTML character
references (MDX decodes references inside quoted attribute values, and
unlike JSON.stringify it does not rely on backslash escapes, which JSX
strings do not honour). Use it for both the Source accordion title and
the preview iframe title, and regenerate the catalog pages.
Regenerated with `npx tsx scripts/generate-catalog-pages.ts`; the only
change across the 399 pages is the one Accordion title line each.

## Install
|

|
|
<InstallCommand command="npx hyperframes add titlecard-calm" item="titlecard-calm" />
|

That writes one file: `compositions/components/titlecard-calm.html`.

titlecard-calm: HyperFrames video primitive (typography / calm / orient)
|
|
|
|
Concept: a restrained title card led by a small mono kicker and a large
|
|
grotesque headline. The kicker fades and rises first, then the headline
|
|
follows. Typography and negative space carry the frame.
|
|
|
|
Variables:
|
|
- headline (string, default "Less, but better"): the primary title.
|
|
- kicker (string, default "DESIGN PRINCIPLE"): the small uppercase label.
|
|
|
|
Envelope: fixed IN and OUT with an elastic HOLD only.
|
|
IN_BASE = 1.20s. Kicker arrives first, headline follows.
|
|
HOLD = max(0, D - IN - OUT). The lockup drifts barely upward.
|
|
OUT_BASE = 0.55s. The full lockup fades with a small rise.
|
|
If D is shorter than IN_BASE + OUT_BASE, IN and OUT compress together.
|
|
Longer mounts stretch HOLD only. The timeline is never time-scaled.
|
|
|
|
Mount contract: the runtime clones only this template. #root fills the
|
|
host box, establishes the container query basis, has no data-width or
|
|
data-height, and registers one paused timeline under the hardcoded
|
|
titlecard-calm id.

## Paste it into your composition
|
|
|
|
Open `compositions/components/titlecard-calm.html` and copy what is inside into your own composition.
|
|
|
|
A component has no size or duration of its own. It takes both from the composition
|
|
you paste it into.
|
|
|
|
## 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 |
|
|
| --- | --- | --- | --- |
|
|
| `headline` | `Less, but better` | string | Primary title displayed in the card. |
|
|
| `kicker` | `DESIGN PRINCIPLE` | string | Small uppercase label displayed above the headline. |
|
|
|
|
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="titlecard-calm"
|
|
data-composition-src="compositions/components/titlecard-calm.html"
|
|
data-variable-values='{"headline":"Less, but better","kicker":"DESIGN PRINCIPLE"}'
|
|
></div>
|
|
```
