```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

## Documentation

### Layout Shift Prevention

width and height on <img> even with CSS sizing — browser reserves space before load
aspect-ratio in CSS as fallback — for responsive images without dimensions

### Form Gotchas

autocomplete attribute is specific — autocomplete="email", autocomplete="new-password", not just on/off
<fieldset> + <legend> required for radio/checkbox groups — screen readers announce the group label
inputmode for virtual keyboard — inputmode="numeric" shows number pad without validation constraints
enterkeyhint changes mobile keyboard button — enterkeyhint="search", enterkeyhint="send"

### Accessibility Gaps

Skip link must be first focusable — <a href="#main" class="skip">Skip to content</a> before nav
<th scope="col"> or scope="row" — without scope, screen readers can't associate headers
aria-hidden="true" hides from screen readers — use for decorative icons, not interactive elements
role="presentation" on layout tables — if you must use tables for layout (you shouldn't)

### Link Security

target="_blank" needs rel="noopener noreferrer" — noopener prevents window.opener access, noreferrer hides referrer
User-generated links need rel="nofollow ugc" — ugc tells search engines it's user content

### SEO Meta

<link rel="canonical"> prevents duplicate content — self-referencing canonical on every page
og:image needs absolute URL — relative paths fail on social platforms
twitter:card values: summary, summary_large_image, player — not arbitrary

### Common Oversights

<button type="button"> for non-submit — default is type="submit", triggers form submission
<dialog> element for modals — built-in focus trap and escape handling
<details> + <summary> for accordions — no JS needed, accessible by default
Void elements don't need closing slash — <img> not <img /> in HTML5, though both work
