Fix hugo layout in hugo > ~0.130.0

For some reason, newer hugo versions have trouble with .summary, and on
some pages where .summary is not defined in the page header metadata,
when rendering the page as a preview card, hugo swallows the card's
closing </div> tag. Such a weird bug, we now just work around it by
explicitly setting the .summary meta on pages that cause this bug(?) to
surface.

+summary: >
+    After the `multichannel LED driver`_ was completed, I was just getting used to controlling LEDs at 14-bit resolution.
+    I liked the board we designed in this project, but at 32 channels it was a bit large for most use cases. Sometimes I
+    just want to pop a piece of LED tape or two somewhere, but I don't need a full 32 channels of control. I ended up
+    thinking that a smaller version of the 32-channel driver that didn't require a separate control computer would be
+    handy. So I sat down and designed a variant of the design with only 8 channels instead of 32 and an on-board ESP8266_
+    module instead of the RS485_ transceiver for WiFi connectivity.
