v1.5.19 - Bigger icons and section headings

New features

• Feature grid icons render at the size you made them. Previously every icon was shown at 64×64 whatever you uploaded. Now anything between 64 and 256 pixels displays at its own size, so a bigger file gives a bigger icon. Smaller files are lifted to 64 and larger ones capped at 256, so nothing comes out unusably small or overwhelming its card. Add @2x or @3x to a filename and the theme divides accordingly, which is how you get a crisp icon from a photo-style file. See The feature grid.
• Non-square icons — a wordmark, a wide logo — now work in a grid pinned with feature-grid--icons, keeping their real proportions instead of being squeezed into a square.
• A new #lists-no-headings tag removes the tag-name heading above each generated post list on a page. Useful when your own content already introduces a single list. See Post feeds and archives.

Bug fixes

• Links to your own site open in the same tab again. The feature grid and feature tab bar were opening every link in a new tab, including links to your own pages. Product cards used outside those blocks had the same problem and are fixed too. Links to other sites still open in a new tab, and you don't have to set anything — it's decided from the address.
• The page and post excerpt wraps naturally again. It was being balanced into even-length lines, which suited a heading but left the first line short of the column. Headings and card descriptions still balance, where the effect belongs.

Under-the-hood improvements

• The description under a full-width header block or sign-up block now balances its line breaks, so it no longer leaves a single word stranded on the last line.
