Design system

Derive surfaces from the colour axis and use the ink generated for each surface.

• Component CSS consumes its own aliases from tokens.css, not source colour tokens or literal colours.
• Use high ink for primary content and supporting ink for small readable labels. Low ink is available for lower-emphasis decoration; it is not a substitute for supporting text.
• Keep borders, focus and selection token-controlled. Do not use the accent as a text-bearing fill without a verified matching foreground.

42dot Sans and a shared modular scale give each text role a consistent size.

• Map feature aliases to semantic type roles; do not invent local font sizes for an existing role.
• Heading levels describe document structure, not visual size. Keep one page h1 and a meaningful heading order.
• Keep rem-based sizing and allow text to wrap when the visitor increases their text size. The scale slider here is a local demonstration.

Profile

A nested curve follows the outside curve, its padding and the border between them.

• For inset shapes, subtract padding and border from the outside radius and clamp at zero.
• Keep corner shape and radius controlled by the owning component aliases. The geometry sliders illustrate the relationship; their values are not saved site settings.

A header and body share an outside silhouette with smaller corners where they meet.

• Use the existing cap geometry: joining corners follow half the outside radius, bounded by the shared maximum. Preserve the independent gap.
• Apply the feature's surface and edge aliases. Do not turn Work, Journal and the other bespoke compositions into one configurable card.

Use the site's prepared Lucide SVGs and the owning control's dimensions.

• Import prepared SVGs from src/icons. Decorative icons are hidden from assistive technology; icon-only actions require an accessible name.
• Use currentColor and component size aliases. Do not restore the archived custom-icon generator or introduce an icon runtime.

Motion explains selection and position; the same state remains clear without animation.

• Reuse SegmentedControl for moving selection and data-hover-list with the existing helper for list highlights.
• Keep focus visible independently of hover. Respect prefers-reduced-motion before starting scripted animation and when it changes.
• The disclosure example and usage notes share native details/summary and the same CSS content reveal and chevron motion. Opening and closing animate where supported, and become immediate with reduced motion; the collection content is illustrative.

Reuse PanelAction for Back, Close and Open controls. Navigation uses links; local actions use buttons.

• The default is a link and requires href. Use as="button" only for an action, never to imitate navigation.
• Supply text for the Back treatment, or label for an icon-only control. The icon choices are close and arrow.
• The buttons here provide local feedback so the examples keep you on this page. Production navigation still uses real destinations. This is not a generic submit-button component.

StudyFrame supplies the real field and button treatment used in Journal studies. Native selects share their own CSS.

• Use StudyFrame around a Journal study; as="div" is available when figure semantics do not fit. Label every input and connect feedback with aria-describedby.
• Use native select elements with class native-select. StudyFrame maps the closed select to the same background and foreground as its other fields; the open menu keeps its own surface pair. Keep feature mappings to --select-*; native browser fallback remains available.
• Contact and tool fields have their own feature contracts. Do not copy the reference page's ds__field or ds__button helpers into a feature, or apply study styling to unrelated forms.

SegmentedControl renders native radios. Checkboxes and the theme switch use established native markup and shared CSS.

• Give each radio group a unique name, a label, two to eight uniquely valued options and a matching selected value. Use disabled for an unavailable group. Named slots can provide option icons.
• Keep native radio keyboard behaviour. The selected value must remain distinguishable with motion disabled.
• Checkboxes use a primitive-study ancestor and data-study-checkbox. Theme switches use the ThemeControls markup and theme-toggle classes, following the range input: off slightly darkens its unfilled track, on uses its filled track, and the solid thumb shares the range thumb fill and dimensions. High contrast uses the range track directly. Keep the thumb flush, without an inset ring. Thumb borders are reserved for high contrast; keyboard focus remains visible in every mode. Neither requires a custom JavaScript state library.

Native range inputs share the site's track, thumb, focus and progress treatment.

• Use a labelled input[type=range] with explicit bounds and an associated output. Keep arrow-key operation native.
• The shell installs range enhancement. Call syncRangeInput when feature code sets a value programmatically.
• The amount meter is an illustrative output, not a reusable progress component.

PanelNavigation groups real Back and Close links, with a slot for contextual actions.

• Supply label and closeLabel. Supply backHref and backText together when the panel has a parent.
• Use the default slot for contextual actions. Enable cap only for a split-stage header; it changes the surrounding stage geometry.
• Keep navigation as anchors so Back, Forward, opening in a new tab and copying a link remain available.

This composition demonstrates a shared selector with a local list/grid arrangement.

• Reuse the selector, not the demo collection as a universal layout. Production collections retain their own feature source.
• The ds-collection classes and sample data belong to this demonstration. List/grid changes must retain readable order, keyboard control and a reduced-motion state.

ScrollFade marks remaining content and clears each edge when there is nothing more to scroll.

• Place data-scroll-fade on the direct scrollable child of ScrollFade. The shell initialises the helper and handles teardown.
• Provide a keyboard-focusable, labelled scroll region when its content needs keyboard scrolling. The feature owns its height and overflow styling.
• Use normal end padding; do not add empty clearance for the fade. Keep content available without JavaScript and respect reduced motion.
