Variation Block out: fix font and color issues

[madhusudhand]

This fixes the following

• limit the max size of the xx-large font to 14rem
• remove color for h2 and set it to post-title
• remove explicit font-size setting to post-title, it inherits the right size with the fix fix spacing in query-loop and post-title size in single/post templates #191
• add duotone for featured-image

Removing the color for h2 turns the heading in the homepage to contrast color which is expected. However, the design suggests the color to be primary which cannot be set in a variation.

Thanks for working on this!

Removing the color for h2 turns the heading in the homepage to contrast color which is expected. However, the design suggests the color to be primary which cannot be set in a variation.

This may be fixed if we change the main heading on the homepage to a h1, as we could set the colour of h1s to primary in the variation.
