v1.0.2 2026-09-04

Corrigida a pré-visualização e as exportações PNG, JPG, WebP e PDF, que saíam espelhadas na vertical: os olhos ficam no canto superior esquerdo, superior direito e inferior esquerdo como no SVG, e os módulos Água, o olho Coração e a moldura Folha aparecem como nas miniaturas de Formas
A verificação de legibilidade espera as formas escolhidas carregarem antes de capturar, então o veredito sempre corresponde ao estilo atual
O modo de leitura pode ser fechado de novo (botão ou Escape), volta para onde você estava e, no celular, rola direto até a área para soltar a imagem
O leitor mantém os textos traduzidos em todos os estados, explica o que fazer no palco e tenta o detector nativo do navegador antes do decodificador local em Rust para fotos de câmera

v1.0.1 2026-09-04

Separados os controles de recolher Conteúdo e Estilo, com os rótulos acessíveis de recolher e mostrar sincronizados
Removido o espaço vazio indesejado no celular causado pela mariposa decorativa ocupar espaço no layout
Centralizadas as abas de ferramentas no celular, mantendo a rolagem horizontal em telas estreitas e traduções longas

v1.0.0 2026-09-04

Rebuilt QR as a workspace: content rail, live stage, and docked style tabs (Colors, Shapes, Effects, Image, Frame, Advanced) with a bottom sheet on phones
Adopted the warm Holi editorial palette and Noto Sans; light, dark, and transparent preview backgrounds plus zoom
Added saved styles (browser-local) with JSON import and export, and style links that travel in the URL fragment only
Added an optional text frame ("Scan me") included in PNG, JPG, WebP, PDF, and SVG exports
Redrew the Capsule, Chain, Water, Pixel modules, the Diamond and Clover eye frames, and the Grid, Star, and Diamond eye balls so each matches its name and keeps the finder ratio scannable
Shape tiles now preview the exact renderer geometry; the Diamond frame warns which eye balls stay scannable
Keyboard shortcuts: Ctrl+S download, Ctrl+Shift+C copy, 1–6 switch tabs
Removed the floating draggable panels and the legacy sidebar

v0.9.1 2026-09-02

Added the transparent moth sketch as QR's quiet product identity
Moved Papers discovery and canonical ownership to Holi Labs
Kept legacy QR paper URLs as redirects to the matching localized Labs reading

v0.9.0 2026-09-02

Removed the unstable outer glow from the shared product dock
Localized QR privacy facts and every shared product control in all seven supported languages
Published the complete engineering-paper index and article in all seven supported languages

v0.8.0 2026-09-02

Fixed brand icons, Generate, Shapes, Colors, Advanced, selectors, and export menus in explicit light mode
Removed system-theme overrides that could make QR controls unreadable after choosing a Holi theme
Made the product dock and shared cards inherit the active QR palette

v0.7.0 2026-09-02

Unified Configuration, Versions, and Privacy in the shared Holi product dock
Added local theme and language preferences plus QR navigation inside Configuration
Placed donations, support, and the visible Shadow Log inside Versions

v0.6.1 2026-09-02

Separated privacy and Version Log into matching floating controls
Moved privacy details into a dedicated drawer and removed the full-width footer bar

v0.6.0 2026-09-02

Added a visible privacy summary across the editor and engineering pages
Clarified that QR content and selected images stay on-device while Cloudflare can observe connection metadata
Synchronized version, Shadow Log, donation, and support surfaces across every QR page

v0.5.0 2026-05-31

Reworked BG, Paper, Ink, and Logo image handling with clearer default sizing and layer proportions
Paper now expands around the ink area, while Background uses a larger outer frame for more predictable composition
Added image thumbnails and quick remove controls for BG, Paper, Ink, and Logo slots
Added Logo fit controls so placed images can fill, cover, or contain the logo area
Added PNG, JPEG, WEBP, SVG, and PDF download options with selectable export sizes
Improved QR style presets, liquid/blur filters, color controls, and gradient behavior
Rebuilt brand logos from deterministic SVG path data with high-resolution WebGL textures and clean contain/reset behavior
Fixed BG visibility, logo container toggling, conic gradient seams, and brand logo preview pixelation
Fixed styled QR copy/export so the generated PNG preserves the visible image, shapes, layers, and WebGL effects
Added a permission-safe copy fallback that shows the generated PNG instead of copying plain text when the browser blocks image clipboard writes
Cleaned project documentation and LLM-facing context files for clearer handoff and project missions

v0.4.0 2026-03-11

Scan Tool: Uploading an image to the Scanner now intelligently displays a preview of the image above the decoded text
Improved rendering performance by optimizing WASM payload configuration (wasm-opt) and allocation strategies
Now uses the modern native BarcodeDetector API for scanning, falling back to a performant WASM-based ZXing decoder
UX: Added smart Z-Index management so active floating panels naturally come to the foreground on click
UX: Uploading a Custom Background image now automatically conceals the Paper layer to guarantee immediate visibility
UX: Advanced Mask Patterns are now labeled with human-readable descriptions rather than mathematical notation
Editor: Removed the redundant 'Layers' panel entirely. Transparency and visibility layers are now fully managed natively within the 'Image' panel
Removed obsolete wee_alloc from WASM crates in favor of the default performant memory allocator
Removed legacy jsqr dependency from the frontend, dropping main-thread execution weight

v0.3.0 2026-02-08

Image slots now support BG/Paper/Ink/Logo with transforms + opacity
Rebuilt shapes system (10 body + 10 eye frame + 10 eye ball) with improved icons
Added 'alive' body shapes with neighbor/corner-aware chaining and tuned readability

i18n migration + English/Spanish support
SVG export is now real vector SVG (not a PNG embedded in SVG)
Unified wasm-qr-svg loading with a single dynamic loader (removed mixed import warning)

Improved perceived performance with idle-time WASM prefetch on first user intent

v0.1.1 2026-01-12

Fixed WebGL shader compilation errors
Resolved 'Outdated Optimize Dep' issues

v0.1.0 2026-01-12
