Apple
Apple's design discipline has been carried by spatial restraint more than any single ornament. The system's identity sits in what it leaves out — generous whitespace, type sized for editorial calm, surfaces tuned to defer to whatever they host — across decades when the rest of consumer software has favored density and decoration.
Glass Edition
Apple's dark mode is a study in restraint: glass surfaces over deep canvases, blur doing the work that ornamentation usually does, type sized for editorial calm rather than UI density. This atmosphere reads the system at its most immersive — the iPhone Pro page or the Vision OS chrome — where the surface is meant to recede behind the content it frames. Glass physics carry it; the chassis never asks to be noticed.
Install at runtime
Run this snippet in any browser console where Void Energy is loaded (or paste it into your app's bootstrap). The atmosphere registers with the engine and renders immediately as a temporary preview — it persists in the visitor's preferences only if they Apply it site-wide.
Physics: glass

Density: x1.12
Live preview
A believable product moment rendered against the active atmosphere. Hover, focus, and toggle the controls — typography weight, button tracking, corner radii, and motion timing all carry the brand's identity.

Typography
Headings, body, and signal text rendered against the active atmosphere.
Typefaces
The active heading and body families — brand override first, atmosphere default second.

Inter
Heading scale
Six levels, each picking up the brand's weight, tracking, and transform tokens.
h1 — Apple
h2 — Glass Edition
h3 — Subsection
h4 — Section header
h5 — Subheading
h6 — Minor subheading
Body & secondary text
Standard reading copy and supporting metadata.
Paragraph — body typography, dim color. Standard readable text for descriptions and content.
Small — small typography, mute color. Used for captions and metadata.Caption — caption level utility class.
Brand overrides
Beyond the typeface, brand profiles can tune weight, tracking, and text-transform per
role. Display covers h1/h2, Heading covers h3/h4, Body covers paragraphs and small
text, Button covers all .btn-* labels. Anything not declared
inherits from the atmosphere's defaults.
Supported overrides & this brand's values
A brand profile can override 4 weights, 4 trackings, and 3 transforms (Body has no transform — prose never gets uppercased).

Palette & shape
The color palette, corner geometry, and motion curves under the active atmosphere. Atmospheres change the values; the architecture never moves.
Energy — Brand axis
The two colors that change most per atmosphere. Primary drives CTAs, focus rings, and headings. Secondary tints hovers, press feedback, toggle thumbs, and the selected channel in the live preview above.
energy-primaryenergy-secondarySurfaces
Background layers from the depth model. Canvas is
the floor — sunk and spotlight are its recess and ambient variants. Surface is where floating elements live. Every tile carries --border-color at var(--physics-border-width), so the border tier is
visible on each outline.
bg-canvasbg-sunkbg-spotlightbg-surfaceSignal — Text hierarchy
Three emphasis levels for information hierarchy.
Color extensions
Two additional palettes layered on top of the five-layer system. Neither is a brand-axis variable, so they don't change much per atmosphere.
Semantic — success, error, premium, and system carry the same meaning on every brand. Most brands inherit the defaults; the rare override applies when a brand's primary hue would clash (e.g. a green primary forces a different success green).

Informational
Data palette — 8 categorical slots derived from primary
Hue-rotated 45° per step from --energy-primary in
OKLCH. Cool atmospheres yield cool-leaning palettes; warm yield
warm-leaning. Use for chart series, chips, tags, kanban columns,
avatar fallbacks, and calendar categories — anywhere
unrelated-by-severity data needs distinct identity. Not for severity (data-3 means
"third slot," not "success"). Auto-contrast handles text color on
any bg-data-* tile.

All five radius levels, rendered with the active atmosphere's tokens. Brand-overridden values are emphasized.

Brand profiles can also override the system's speeds and easing
curves. The square below uses --speed-slow and --ease-spring-snappy — both carried by the brand axis
when set, otherwise inherited from the active physics preset. Hover the demo to play.
Supported overrides & this brand's values
A brand profile can override 3 speed levels and 4 easing curves. Anything not declared inherits
from the active physics preset (glass / flat / retro). Cascade
delays (--delay-cascade, --delay-sequence) are physics-only and not part of
the brand axis.
