The theme mode's preview sheet (spec/14 §20.3, D-139): fixed sample charts drawn through the theme being edited, and the designs a person adds from the store.
A theme is judged against everything it must serve, so the samples cover what a theme
carries — the categorical series, the five roles, the thermal and diverging ramps, and
axes, grid and text — and a card of the chrome's swatches. Each is drawn through the
ordinary path, Visualize.Chart.apply/2 then render/2, with resolve: :literal, so
the sheet shows the edited theme and no stylesheet of the host's page re-points a slot
under it.
This module compiles only when Phoenix.Component is loaded (spec/10 §1.1, D-45, D-85).
Summary
Functions
The theme with every ramp it cannot draw — fewer than two anchors, an anchor that is not a colour — and an empty series replaced by the default theme's, so a sheet always draws while the editor names the fault (spec/14 §20.3).
The fixed samples (spec/14 §20.3), each %{id, title, design, sources}: categorical
series, a status chart in the five roles, a thermal and a diverging chart, and a titled
chart of axes, grid and text.
Renders the preview sheet (spec/14 §20.3): <div class="vis-builder-theme-sheet"> of
<figure class="vis-builder-theme-sample"> cards — the chrome's swatches, each fixed
sample, then each design from the store with its × — and the form that adds a design.
