Autoflow rule: skip checks

When autoflow does NOTHING — explicit directives, code, custom blocks.

When they fire

Autoflow runs three skip checks before any rule. If any check passes, autoflow leaves the slide untouched.

Check	Trigger
explicit	Slide already has #[fit], ![right], position modifiers, [.autoscale], or [.alternating-colors]
code	Slide contains a fenced code block (```)
custom-block	Slide contains a :::columns, :::diagram, :::steps, :::center, or :::math block

Why

The user already told autoflow what they want. Don’t override intent.

# Cover

These slides demonstrate the SKIP CHECKS that bypass autoflow entirely.

---

<!--
SKIP: explicit
The slide already has explicit layout directives, so autoflow does nothing.
The user knows what they want.
-->

#[fit] I asked for #[fit] explicitly

Autoflow won't touch this slide.

---

<!--
SKIP: code
A code block is a strong signal of intent — don't reflow it.
-->

# A code example

```js
function sum(a, b) {
  return a + b;
}
```

---

<!--
SKIP: custom-block
:::columns / :::diagram / :::steps / :::center / :::math
all bypass autoflow because they're explicit layouts.
-->

# Two columns

:::columns
First column with some text that lays out beside the next.

Second column with different text.
