v0.4.0

The redesign release: unified primitive API, full accessibility, design token system, object-copy model, responsive mobile support, and a guarantee-grade conformance checker.

Context

A comprehensive external critique identified structural gaps in the framework:
no custom form controls, no ARIA semantics, hardcoded CSS values, no mobile
support, no RTL readiness, and a conformance checker that could be bypassed.

A 12-phase charter addressed every finding. The primitive API was unified
around factory functions returning {el, methods, destroy()}. A kernel module
centralized escape-stack and overlay management. Design tokens replaced all
raw literals. The barrel was split into core and extras for tree-shakeable
imports. Every primitive was rebuilt with APG-compliant keyboard and ARIA
patterns. A runtime auditor and expanded conformance checker close the loop
on charter guarantees.

Breaking

• Breaking. Unified primitive API: toggleWidget replaced by createSwitch, Select class replaced by createSelect, segmented replaced by createSegmented/createTabs. All primitives now return {el, methods, destroy()}.
• Breaking. Gallery migrated to createTabs; Select class replaced by createSelect factory with full APG combobox pattern; dead legacy segmented() function removed.
• Breaking. Barrel split: core (tinymoon) and extras (tinymoon/extras). createSettings, createWikiView, api, post, renderDocMd moved to extras. fmtTime removed. Root index.js re-export shim deleted.
• Breaking. cssVar moved from settings.js to kernel.js. New kernel module centralizes escape-stack, overlay placement, root-element creation, and CSS variable access.

Features

• New primitives. createCheckbox, createRadio, createFileInput, createDatePicker (APG grid pattern), createTabs -- all form-participating (except tabs), with full ARIA semantics. Tooltip split into plain-text tooltip and rich hovercard.
• Accessibility. Modal rebuilt on native <dialog> with focus trap, Escape, aria-labelledby. Toast gets aria-live, dismiss button, pause-on-hover, stack cap. Context menu gets role=menuitem, Shift+F10 keyboard entry, focus restore. Shell gets skip link, route announcer, aria-current.
• Design tokens. Rem-based type and spacing scales, duration tokens, z-index tokens, line-height and font-weight tokens. Single accent hue via color-mix() derivation. All raw CSS literals replaced with token references.
• Object-copy system. Focusable data objects with Ctrl+C support, automatic context-menu Copy entries, selection model (.doc-body user-select: text), and print stylesheet.
• Content-first. All semantic HTML styled by default with identity tokens. Declarative string-view path for the shell. Sidebar drawer JS toggle for mobile hamburger menu.
• Responsive and i18n. Full mobile support with drawer nav, dvh, 44px touch targets. Logical CSS properties for RTL. Non-Latin font fallback policy. color-scheme declarations for native UI matching.
• Conformance checker. Template-literal URLs, importmaps, additional attributes, color functions, WebSocket schemes, encoding errors -- 6 bypass classes closed and 3 false-positive classes fixed.
• Runtime conformance auditor. Dev-mode module checking border-radius, native controls, and network loads at runtime.
• Selector hygiene. CSS rules scoped, deduplicated, and unified across all stylesheets.
• TypeScript declarations. index.d.ts for core barrel.
• Top layer and input styling. Context menu and popover promoted to top layer via popover=manual. Number and range input styling added.
• Test infrastructure. Playwright + vitest + axe-core test suite. Zero-network, reduced-motion, responsive, RTL, and accessibility CI. Go embed/Handler tests. Characterization baselines and red-green bug tests.

Fixes

• Fix. Escape multi-close bug: pressing Escape in a Select inside a modal no longer closes both.
• Fix. copyButton now awaits clipboard write before showing success state.
• Fix. icon() now throws on unknown name instead of silently returning empty string.
• Fix. registerCtx throws on duplicate key; renderMiniMd renders non-hash links as plain text; api() checks r.ok and post() no longer silently coerces bad JSON; router catches malformed percent-encoding in hash.
• Fix. WCAG AA contrast: --text-faint, --on-accent, --border-2 adjusted to pass 4.5:1 / 3:1 in both themes.
• Fix. prefers-reduced-motion support: blanket suppression of transitions and animations, scroll-behavior override.
• Fix. RTL layout: switch knob and toast translateX flipped for :dir(rtl).
• Fix. ensureRoot now applies attributes even if element already exists. Wiki deep-link highlight no longer persists after refreshCurrent().
• Fix. Axe violations: aria-label on theme button, tabindex=0 on scrollable main.
