miga-heygenandMiguel Ángel 7b5fdb1ad2 fix(docs): emit catalog source accordion titles as plain strings (#4006)
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.

Oversized Cursor (actor primitive), mountable sub-composition
concept: a deliberately oversized macOS-style pointer that enters the frame
from off-screen, travels in one continuous glide to a target, taps it (the
click ignites a visible reaction on the target itself), drifts aside during
the dwell, then exits off-screen. One mechanic: a pointer-driven click that
visibly causes something. Family: pointers. Profile: interaction.
compiled-from: spec ready (oversized-cursor SKILL.md, ~/Downloads/oversized-cursor);
actor file mechanics compose (size/look, entry law, tip-targeting, click-ignition,
exit law).
use-when: kicking off a UI scene, igniting a morph/transition/typing run with a
causal click, or carrying the eye across a scene that would otherwise read as
static or stale.
mount contract: this file is a HyperFrames sub-composition, loaded by a host via
data-composition-src, never opened standalone. The runtime clones ONLY the
<template> contents into the host slot (see
skills/hyperframes-core/references/sub-compositions.md); everything outside
<template>, including this <head>, is discarded at render. The root is #root:
elastic, no data-width/data-height declared here, it fills whatever box the host
clip gives it (position:absolute; inset:0). See demo.html for the mount usage
(data-composition-src="./oversized-cursor.html" on a sized host clip).
variables:
cursor_variant (enum light|dark) pointer fill/stroke pairing, pick per scene contrast
target_x, target_y (number, percent of the HOST box) the tip's landing point
click_label (string) label on the target the cursor clicks
exit (enum none|fade|up, default none) optional whole-stage departure during
OUT; the cursor's own off-screen exit always plays (it is the mechanic)
envelope (of data-composition-duration, default 4.2s):
IN 0.00s to 1.17s (fixed) off-screen entry glide (0.85s) then click tap (0.32s)
HOLD 1.17s to D-0.60s (elastic) click ignition plays, cursor drifts aside, then dwells
OUT D-0.60s to D (fixed) cursor accelerates off-screen; with exit fade|up the
whole stage (target included) also departs
sound: one click tap SFX (soft UI click) fires at the click moment, the fixed
offset into IN documented below as SYNC POINT. This file never plays audio: it
only marks the cue's timing for the mix stage to pick up.

## Paste it into your composition
Open `compositions/components/oversized-cursor.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 |
| --- | --- | --- | --- |
| `cursor_variant` | `light` | `light`, `dark` | |
| `target_x` | `55` | 15% to 85%, step 1% | |
| `target_y` | `55` | 15% to 85%, step 1% | |
| `click_label` | `Generate` | string | |
| `exit` | `none` | `none`, `fade`, `up` | Optional whole-stage departure. Default none: the ignited target stays 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="oversized-cursor"
data-composition-src="compositions/components/oversized-cursor.html"
data-variable-values='{"cursor_variant":"light","target_x":55,"target_y":55,"click_label":"Generate","exit":"none"}'
></div>
