Changelog

A parallel JavaFX library for native thick-client (desktop) C3 operator apps — C3 and its extension packs only. All 44 stable components are implemented at spec parity with the web, plus the C3 App Shell template and all nine RC3 (Robotics & Autonomy) extension-pack organisms — including a dependency-free Canvas reference renderer for the perception view. Themes are derived additively from the same token CSS; the React components and tokens are read, never modified. Explore it at /c3/javafx.

Clearing the search field now brings back every command. Previously, once a group filtered down to no matches it stayed hidden, so emptying the query could leave the palette stuck on “No results found.”

Switch, Checkbox, Radio Group, Tabs, Slider, and Navigation Menu now correctly dim and block interaction when disabled. The styling previously targeted the native `:disabled` pseudo-class, which these Base UI–backed controls don't expose.

Focus-visible rings across all components are now 1px with a tighter offset (previously 2px with a wider offset), for a lighter, less obtrusive focus affordance.

The Select dropdown now opens directly below the trigger instead of aligning the selected item over it, which made the popup jump up or down depending on the current selection.

PRIZM's first extension module pack — an identity layer plus domain-specific organisms layered on C3 without forking foundations or primitives. Activates via `data-pack="rc3"` (overrides only the accent tokens to the Ember signature colour, oklch(71% 0.195 32); everything else inherits from C3). Ships an always-on identity rule, three concept docs (command contexts, behavioural invariants, surface regions), nine signature organisms (safety actions, comms / health strip, autonomy mode selector, video tile, telemetry HUD, controller interface, platform roster, platform detail, perception view), and two anchor templates (operator console, fleet overview). Lives at `/c3/rc3`; sources at `components/rc3/<slug>.tsx`, LLM context at `llms/rc3/<slug>.md`.

PRIZM.md and llms.txt updated so AI assistants applying PRIZM C3 to a consumer project now scaffold from the C3 App Shell template by default, rather than composing primitives from scratch. The shell already shipped on 2026-05-16; this closes the gap in the instruction layer.

Chrome and panel blur reduced from 12 / 24 px so underlying canvas activity (map markers, route lines, terrain) stays readable through glass. Aligned with Apple's thin material tiers.

Single search input replaces the trigger + popup-input pattern. Type to filter against the items prop; pick to select. Popup width pinned to the trigger, empty state collapses cleanly.

A C3-only translucent surface system in two tiers (chrome for the application frame, panel for floating overlays). Light and dark modes, noise overlay, hairline border, rim-light highlight. Six components opt in via variant='glass'.

Documents the lucide-react choice, the site-wide stroke-width of 1.5, the five-size scale, accessibility conventions, and the PRIZM brand mark as a worked example for custom SVGs.

First C3 template. Top bar, status ticker, icon rail, slide panel, notification centre, workspace panel — all composed from existing PRIZM primitives. Includes the Design Principles Applied section anchoring decisions in HF research.

All 44 primitives ported and marked stable.

Design principles, Colours, Typography, Surface & motion shipped as the visual reference layer.
