0.6.2 — 2026-06-02

Restored edge splitting for docked panel groups when dragging panel tabs or tearoffs onto a docked pane edge.
Kept floating tearoff targets tab-only while allowing tearoffs to dock to the app/window left, right, top, and bottom edges.
Reduced window-edge dock previews and initial pane sizing to a smaller sidebar/shelf estimate instead of a half-screen split.

Fixed tearoff tabs that could not be moved or re-docked consistently after becoming floating panels.
Fixed re-docking between tearoffs so tabs insert before toolbar/free-space chrome and do not leave dead copies in the document view.
Fixed single-panel tearoff behavior: floating tearoffs collapse to a title-only panel when reduced to one tab, while docked panel groups keep their one-tab tabbar.
Fixed tearoff drop targeting so floating tearoffs only accept add-tab drops, never vertical or horizontal split drops.
Fixed floating tearoff containment so panels stay inside the document content area instead of covering document tabs, toolbars, or sidebar docks.
Fixed floating panel and toolbar z-order so the last selected movable surface is topmost and the rest are compactly ordered beneath it.
Fixed panel toolbar placement and active-tab toolbar switching across docked and floating panel states.
Fixed nested inspector-style tabpanels so panel-specific content is hidden with its owning tab instead of leaking into sibling tabs.

Dark native scrollbars/controls leaked into light host pages: color-scheme: dark was on :root. It's now scoped to .dcs, and the decius-web theme declares color-scheme: light. .dcs regions stay dark; the host keeps its own scheme.

First public release.

Core framework decius.css (scoped to .dcs): panels, dock/split, buttons, inputs, sliders & faders, knobs, checks/switches, badges/tags/chips, kbd, alerts, modals, trees/tables/lists, toolbars, tooltips, color swatches & pickers, curve & node-graph editor surfaces, subpanels, foldouts, menus/dropdowns/context menus, popovers, toasts/notifications, and skeuomorphic hardware elements.
decius.js — a zero-dependency vanilla component runtime with a Bootstrap-style data API (data-dcs-*) and a programmatic API (decius.toast, decius.modal, decius.menu, …). Drives collapse, modals, menus, popovers, tabs, toasts, dismiss/close, toggles, and the drag controls. Ships as IIFE (global decius), minified, and ES module.
One-archive download decius-css.zip (css + js + fonts) and a kitchen-sink.html example.

Light web/docs theme decius-web.css (--dw-*).
Icon web font built from 225 source stroke icons (<i class="di di-name">).
