# Presets

Choose a document direction, supply an accent, and render a real PDF with the
same explicit font-registration step used by Rendro's shipped recipes.

## Start with a Swiss invoice

This Invoice/Swiss/`#2C6BED`/light path is the canonical first success. It uses
the formatter-owned source shared by the configurator and Livebook, so the
selection you copy stays aligned with Rendro's supported preset syntax.

```elixir
# rendro-theme-snippet:start
preset = :swiss

theme =
  Rendro.Theme.preset(preset, accent: {44, 107, 237}, mode: :light)

document =
  invoice
  |> Rendro.Recipes.Invoice.document(theme: theme)
  |> Rendro.Theme.Presets.register_fonts(preset)
# rendro-theme-snippet:end
```

Each preset is a strong starting point: choose a style, supply your accent, and review the rendered document for your content. Presets are not design-quality, accessibility, PDF/UA, WCAG, or print-safety guarantees.

`Rendro.render/2` can now render `document` deterministically. The explicit
`register_fonts/2` call keeps the document responsible for the curated fonts it
embeds; it is not a global registration step.

## Choose a direction

Rendro provides six strict preset constructors. They are starting directions,
not a ranking or an approval of a document's final visual quality.

| Preset | Structural direction | Font-role character | Density / geometry | Business-document fit |
| --- | --- | --- | --- | --- |
| Swiss | compact grid with direct hierarchy | grotesque headings with practical body copy | dense, aligned, and economical | product and SaaS invoices |
| Humanist | open service-document structure | humanist sans roles with a readable rhythm | relaxed spacing with familiar forms | service summaries and client records |
| Editorial | narrative report frame | text-serif emphasis with restrained supporting sans | measured columns and reading-led pacing | reports and correspondence |
| Corporate Classic | formal record layout | serif-and-sans balance for established institutions | steady proportions and conventional grouping | traditional business records |
| Minimal Mono | operational reference grid | restrained monospace roles | regular columns and deliberate geometry | operational and technical artifacts |
| Brutalist | direct, high-contrast frame | geometric roles with blunt emphasis | assertive blocks and visible structure | deliberate internal artifacts |

## Continue by job

- [Browse bounded previews and copy a selection](https://hexdocs.pm/rendro/assets/rendro/configurator/index.html)
  in the static configurator. It is the browse → pick → copy route, not a
  second rendering tutorial. A catalog preview is bounded evidence: it is not
  complete-document or universal-viewer proof, and a representative-accent
  preview is disclosed as representative rather than your requested accent.
- Generate an application-owned module with `mix rendro.gen.theme`, commit it,
  then use `--check` to keep the committed source from drifting.
- [Render, inspect, and download an invoice in Livebook](livebook/first_invoice.livemd)
  to execute one real document and inspect its bytes.
- See [Theming](theming.md) for manual tokens and `from_brand/2`, or
  [Branding](branding.md) for caller-owned logos and fonts.
- Read [API Stability and Support Boundaries](api_stability.md) before turning
  a supported capability into an operational or compliance assumption.

## Read the evidence state

The configurator describes a preview as exact, representative-accent, or
unavailable. Copied code always names the requested selection. Dark output
retains the visible boundary: **Screen-oriented; not a print, accessibility,
PDF/UA, or WCAG claim.** Catalog quality labels are limited to **Scored —
passes current rubric**, **Scored — needs work**, and **Not yet scored**. They
are dispositions, not approval or certification.

Deterministic bytes, bounded catalog previews, human quality dispositions, and
documentation claims are separate evidence levels. A valid snippet vocabulary
or a page-one raster does not establish broad visual, accessibility, PDF/UA,
WCAG, print-safety, or universal-viewer guarantees.
