The variety release

Data, Aligned

V3.7 gives every card more ways to fill the same grid: charts, numbers, and a cover that can open with an eyebrow.

Range, without breaking the system. The shape held; v3.7 just widened what can sit inside it.

The chart blocks were catalogued for a year. Now they actually render, in both paths, on the same gray ramp as everything else.

The system in four numbers

One grammar, many parts.

blocks

families

ADRs

render paths

Where the blocks live

Editorial carries the most weight.

One bar goes full-ink: the family a card reaches for most.

How a chart stays on brand

Grayscale, single emphasis. A chart obeys the same rules as prose: every bar and line sits on the gray ramp, and exactly one element goes full-ink to carry the focus. No color, no second highlight.

Rules per release

The spec grows in small, deliberate cuts.

Table or chart

Pick by what the reader extracts.

	Table	Chart
Reads as	values	shape
Best for	exact figures	magnitude at a glance
Carries focus with	a bold cell	one full-ink bar

Colors on the canvas

The ramp is the whole palette.

Charts changed nothing about the rule that has held since v3.0:

colors. Every bar, line, and number stays on the gray ramp, and one focal element per chart carries the emphasis.

Reach for the right one

What you have decides the block.

You have	Reach for
One number that matters	stat-callout
A few parallel metrics	stat-grid
Magnitudes to compare	bar chart
A trend over time	line chart
Takeaway	Shape first, text last: the data picks the block.

Bottom line

More range, one grammar.

V3.7 adds charts, numbers, and a cover eyebrow without a single color or a broken grid. The system gets more expressive the same way it got quieter: by rule, on the ramp, one emphasis at a time.
