closes https://github.com/TryGhost/Ghost/issues/12770
AMP pages can't contain bare `<style>` tags, they need to have an attribute like `<style amp-custom>` and there can only be a single `<style amp-custom>` tag in the output.
- removed accent color style tag output from `{{ghost_head}}` (aliased as `{{amp_ghost_head}}`) when in an AMP context
- added a new `{{amp_style}}` helper that can be used to inject styles into the AMP template
- outputs `:root {--ghost-accent-color: #abc123}` style if an accent color is set
no issue
- The unmatched closing </span> tag is ignored by the browser anyway and is not semantically correct
- Checked the history if there was any possible purpose behind it in the past but doesn't seem like it
refs #11980
This adds a new handlebars helper {{amp_analytics}} which outputs the
GA configuration script if the amp_gtag_id setting is present.
We also update {{amp_components}} to output the GA script in the head if
the setting is present
The featured post images are distorted in the AMP template. This change adds `object-fit:cover` styling, and thus avoids distortion but allows images to scale.
Fixes#11560
