## Overview

#### Purpose and deliverables
Berry is a Sass-authored CSS utility/framework library. Its repository delivers prebuilt stylesheets for direct consumption and the modular Sass source for customization: `css/berry.css`, `css/berry-format.css`, and `sass/berry.scss`.

#### Primary entry points
`sass/berry.scss` is the source composition root: consumers compile it through a Sass implementation to produce a complete Berry stylesheet. `css/berry.css` is the general compiled distribution, while `css/berry-format.css` is a separate precompiled format-oriented variant. There is no application runtime, server, or executable entry point.

#### Sass composition boundary
The source is organized around Sass partial imports under `sass/berry/`. The top-level entry point assembles configurable defaults and module indexes, making module directories the principal dependency boundary. `sass/berry/_style.scss` is the core style aggregation layer; category `_index.scss` files expose each module family, such as `sass/berry/modules/reset/_index.scss` and `sass/berry/modules/utilities/_index.scss`.

#### Configuration and design tokens
Central configuration partials define the values used by downstream generated rules, separating policy from emitted CSS. Key inputs are `sass/berry/config/_typography.scss`, `sass/berry/config/_buttons.scss`, and `sass/berry/config/_utilities.scss`. Changes here propagate during Sass compilation into typography, component, and utility output.

#### Baseline and typography stages
The reset stage establishes cross-browser baseline behavior through `sass/berry/modules/reset/_normalize.scss` and `sass/berry/modules/reset/_border-box.scss`. Typography then defines root, base element, content-block, and print styles via `sass/berry/modules/typography/_root.scss`, `sass/berry/modules/typography/_base.scss`, and `sass/berry/modules/typography/_print.scss`. This layer is foundational; utilities and design modules assume these baseline conventions.

#### Design components
The design module supplies opinionated element/component styling, especially forms and buttons. Its public assembly is `sass/berry/modules/design/_index.scss`, backed by `sass/berry/modules/design/_buttons.scss` and `sass/berry/modules/design/_forms.scss`. Default variants are separately represented, allowing the library to distinguish reusable structural rules from its default visual treatment.

#### Utility generation layer
Utility partials provide composable classes for layout, responsive-like sizing primitives, visual effects, and interaction/display behavior. The aggregation point is `sass/berry/modules/utilities/_index.scss`; major domains include `sass/berry/modules/utilities/_flex.scss`, `sass/berry/modules/utilities/_grid.scss`, and `sass/berry/modules/utilities/_padding-margin.scss`. These consume shared configuration and are intended to be used directly in markup after compilation.

#### Optional/demo and external dependencies
Demo-specific CSS is isolated under `sass/berry/modules/demo/_index.scss`, keeping demonstration/template styling separate from the framework’s core layers. The only material build dependency is a Sass compiler; the repository declares no backend infrastructure, client-side JavaScript runtime, package manager metadata, or external service integration. Documentation is hosted externally at `https://maxsite.org/berry`.
