doc: provide card look for "sections" on features page. Make each section on the features page look like a raised card. Note the sections aren't headers 8-(. The markup is: .. container:: card **pseudo header** - list stuff .. container:: card I can't put: pseudo header ============= in there even though each card is its own section. I would like to have real headers for them (allow text->speech and othr devices easiera access). Starting a header in column 1 seems to be a requirement of the syntax 8-(.
