STATS / card row: the same three numbers, given cards of their own.

WHEN TO USE THIS INSTEAD OF THE INLINE BAND. On a page with no other card
content, where the numbers are the section rather than an aside inside it.
Cards give each number an edge and a surface, which makes three of them read as
a deliberate block. Drop this onto a page that already has a feature grid or a
pricing table and you have two competing rows of cards; use the band there.

WHY THIS OWNS ITS MARKUP, AND WHY IT DOES NOT INCLUDE _stat.html. _stat_band.html
takes a list of dicts, so it needs a view. The tiles it composes each take flat
strings, so a template CAN include brickwork/components/_stat.html once per stat
without any context, and that is a perfectly good thing to do. This example goes
one step further and writes the three cards out by hand, for one reason: it is
the version you can copy, paste and then edit freely, including the card
chrome. If you want the shipped tile treatment instead (tabular numerals, the
trend glyph, the visually hidden direction text), include _stat.html three times
rather than copying this.

WHAT YOUR VIEW MUST SUPPLY: nothing. The numbers are typed in. Replace them with
yours, and keep them honest: a made-up number on a marketing page is a claim you
will be asked about.

EVERY NUMBER NEEDS A LABEL THAT SAYS WHAT IT MEASURES. "94%" on its own is
noise. "94% of invoices paid without a phone call" is an argument. The value is
the headline and the label is the sentence it belongs to, so write the label
first and check the number still answers it.

Headings: this is a stacked section, so the section heading is an <h2> and each
card's label is a plain <p>, not a heading. Three <h3>s of card labels would put
"Average time to pay" into the document outline as if it were a subsection.
