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.

modal-morph: HyperFrames video primitive (structure, Wave M9 experiment)
|
|
|
|
The shared-element grow: a small card expands into a full panel with its
|
|
children re-flowing continuously. FLIP-style: BOTH layouts (card and
|
|
panel) are real DOM, measured exactly ONCE at mount; from then on every
|
|
frame is a pure function of timeline time. The morph interpolates the
|
|
container rect and applies it as transform only (translate + scaleX/Y
|
|
from a fixed top-left origin); container width/height are NEVER
|
|
tweened. Children marked data-morph-key exist in both layouts; each
|
|
panel child counter-scales against the container and translates toward
|
|
the lerp of its own two measured rects, so content re-flows instead of
|
|
stretching. Panel-only furniture fades in late; the card crossfades out
|
|
early in the morph.
|
|
|
|
Card content is a SLOT. Callers supply content by placing an inert
|
|
template anywhere in the HOST page:
|
|
|
|
<template data-slot="modal-morph-card"> ... </template>
|
|
|
|
The slot content is cloned into BOTH the card body and the panel head.
|
|
Descendants carrying data-morph-key are paired across the two layouts;
|
|
slot content without keys is wrapped as one keyed block. With no slot,
|
|
the primitive renders token defaults (accent dot, display title line,
|
|
mono meta line) that re-flow from a stacked card to an inline panel
|
|
header row.
|
|
|
|
Variables (declared in data-composition-variables below):
|
|
- from_scale (number, default 1, clamped 0.5 to 1.5): multiplies the
|
|
authored card footprint before the one-time measurement.
|
|
- expand_at (number seconds, default 1.2): when the grow begins.
|
|
- register ("calm" | "snappy", default "calm"): calm is a smooth
|
|
inOut cubic; snappy is faster with a small settle that never
|
|
overshoots the target rect beyond 1.02.
|
|
- accent ("green" | "blue" | "violet", default "green"): green rides
|
|
--brand, blue rides --accent, violet rides --accent-2.
|
|
- exit ("none" | "fade" | "up", default "none").
|
|
|
|
Envelope, fixed IN and OUT with elastic HOLD only (never timeScale):
|
|
IN_BASE = expand_at + MORPH (0.95s calm, 0.6s snappy) + 0.15s
|
|
HOLD = max(0, D - IN - OUT)
|
|
OUT_BASE = 0.45s only when exit != none
|
|
If D < IN_BASE + OUT_BASE the whole envelope compresses together.
|
|
|
|
Determinism: layouts are measured once, synchronously, at mount; the
|
|
per-update apply recomputes every transform and opacity from tl.time()
|
|
alone (no Math.random, no wall clock, no incremental state). Eventful
|
|
seeks land identical frames in any order and either direction.
|
|
|
|
Mount contract: template-wrapped; #root fills the host box (no
|
|
data-width/height, container-type: size, cqmin units), styled via
|
|
#root only; one paused timeline under the LITERAL "modal-morph" key.

## Paste it into your composition
|
|
|
|
Open `compositions/components/modal-morph.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 |
|
|
| --- | --- | --- | --- |
|
|
| `from_scale` | `1` | number | Multiplies the authored card footprint, clamped 0.5 to 1.5. |
|
|
| `expand_at` | `1.2` | number | Seconds after mount when the card grows into the panel. |
|
|
| `register` | `calm` | `calm`, `snappy` | Morph feel. Snappy is faster with a settle capped at 1.02 of the target rect. |
|
|
| `accent` | `green` | `green`, `blue`, `violet` | Accent color: green rides --brand, blue rides --accent, violet rides --accent-2. |
|
|
| `exit` | `none` | `none`, `fade`, `up` | Optional departure. Default none: the settled panel holds until the frame cuts. |
|
|
|
|
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="modal-morph"
|
|
data-composition-src="compositions/components/modal-morph.html"
|
|
data-variable-values='{"from_scale":1,"expand_at":1.2,"register":"calm","accent":"green","exit":"none"}'
|
|
></div>
|
|
```

|
modal-morph: HyperFrames video primitive (structure, Wave M9 experiment)
|
|
|
|
The shared-element grow: a small card expands into a full panel with its
|
|
children re-flowing continuously. FLIP-style: BOTH layouts (card and
|
|
panel) are real DOM, measured exactly ONCE at mount; from then on every
|
|
frame is a pure function of timeline time. The morph interpolates the
|
|
container rect and applies it as transform only (translate + scaleX/Y
|
|
from a fixed top-left origin); container width/height are NEVER
|
|
tweened. Children marked data-morph-key exist in both layouts; each
|
|
panel child counter-scales against the container and translates toward
|
|
the lerp of its own two measured rects, so content re-flows instead of
|
|
stretching. Panel-only furniture fades in late; the card crossfades out
|
|
early in the morph.
|
|
|
|
Card content is a SLOT. Callers supply content by placing an inert
|
|
template anywhere in the HOST page:
|
|
|
|
<template data-slot="modal-morph-card"> ... </template>
|
|
|
|
The slot content is cloned into BOTH the card body and the panel head.
|
|
Descendants carrying data-morph-key are paired across the two layouts;
|
|
slot content without keys is wrapped as one keyed block. With no slot,
|
|
the primitive renders token defaults (accent dot, display title line,
|
|
mono meta line) that re-flow from a stacked card to an inline panel
|
|
header row.
|
|
|
|
Variables (declared in data-composition-variables below):
|
|
- from_scale (number, default 1, clamped 0.5 to 1.5): multiplies the
|
|
authored card footprint before the one-time measurement.
|
|
- expand_at (number seconds, default 1.2): when the grow begins.
|
|
- register ("calm" | "snappy", default "calm"): calm is a smooth
|
|
inOut cubic; snappy is faster with a small settle that never
|
|
overshoots the target rect beyond 1.02.
|
|
- accent ("green" | "blue" | "violet", default "green"): green rides
|
|
--brand, blue rides --accent, violet rides --accent-2.
|
|
- exit ("none" | "fade" | "up", default "none").
|
|
|
|
Envelope, fixed IN and OUT with elastic HOLD only (never timeScale):
|
|
IN_BASE = expand_at + MORPH (0.95s calm, 0.6s snappy) + 0.15s
|
|
HOLD = max(0, D - IN - OUT)
|
|
OUT_BASE = 0.45s only when exit != none
|
|
If D < IN_BASE + OUT_BASE the whole envelope compresses together.
|
|
|
|
Determinism: layouts are measured once, synchronously, at mount; the
|
|
per-update apply recomputes every transform and opacity from tl.time()
|
|
alone (no Math.random, no wall clock, no incremental state). Eventful
|
|
seeks land identical frames in any order and either direction.
|
|
|
|
Mount contract: template-wrapped; #root fills the host box (no
|
|
data-width/height, container-type: size, cqmin units), styled via
|
|
#root only; one paused timeline under the LITERAL "modal-morph" key.
