BFlat	8da68b009c	Desktop create pages redesign: shared generation feed, embedded model selector, gallery folders sidebar (#1635 ) ## Summary Reworks the desktop (Tauri) app's Create Image / Create Video pages to match the webapp, extracts the webapp's generation gallery into a shared library used by both apps, embeds the model selector into every prompt box, adds a folders sidebar + marquee selection to the gallery modal, restyles the login/pricing/credits modals to the webapp look, and turns the Apps page into the default landing tab. ### Shared generation-list lib - Extracted the webapp's generation feed into `@storyteller/ui-generation-list`: list + masonry grid views, pending/failed/completed rows and cards, thumbnail handling, gallery/prompt data hooks, and the shared grid/list view store + toggle. Host-specific actions (recreate, make-video, share, download, toasts) inject via render props — webapp markup unchanged, its old files are now thin wrappers. ### Desktop create pages - Prompt box fixed at the bottom, `max-w-5xl` like the webapp; pages renamed to "Create Image" / "Create Video". - Generation feed: in-progress/failed from the Tauri task queue, history from the library API, rendered as grid or list (toggle in the TopBar next to credits). Typed Tauri completion events push finished media in instantly; the poll reconciles and dedupes. - Row/card quick actions (recreate, make video, copy link, download) backed by a shared `desktopMediaActions` module extracted from the TopBar gallery wiring. - Hero + background act as a splash that fades when the feed loads; bottom gradient behind the prompt box. Batch generations show "Generating N images" on the single pending chip. - Video prompt box now expands vertically as far as the image prompt box (viewport-relative). ### Embedded model selector - `ClassyModelSelector` gained `variant="embedded"`: a compact pill that opens the webapp-style rich-list popover while keeping the desktop's provider selection. Embedded on all five prompt-input pages; floating selectors removed; legacy "10 sec." badges dropped. ### Gallery modal - Left sidebar lists the user's folders (drag-and-drop, right-click management, new-folder button) and shows on the Folders tab too, highlighting the active folder's root branch. - Marquee (drag-rectangle) selection in view mode, with edge auto-scroll; starts only on blank background so it doesn't interfere with drag-to-folder/canvas. ### Restyled modals (desktop) - Login/signup: webapp 2-column layout (form left, Vimeo showcase right), no Google button (Google auth isn't wired for Tauri), `artcraft-icon` logo, eye toggles. The dismiss button is removed so login is required; the post-auth Discord + Success onboarding steps are kept, as is the existing Tauri auth flow. - Pricing + credits: match the webapp visually (unified monochrome plan cards with Most Popular / Best Value highlight frames; `#161618` credit-pack cards with Popular badge). All billing stays on the existing Tauri `invoke` calls — no billing logic changed. ### Apps page / navigation - The Apps page is now the first tab and the default landing tab, with a Home icon. Restyled to the webapp home: "What will you craft today?" hero, Create / Edit sections, gradient-hover cards sized to their content, full-width scrollbar. The TopBar quick-menu header reads "Create" instead of "Generate". ### Fixes - Video Editor no longer crashes on the desktop app (`Tooltip must be used within TooltipProvider`): the editor shell now mounts its own Radix `TooltipProvider`. The webapp got one app-wide via `SidebarProvider`; the Tauri app had none, so panel tooltips threw. ### Misc - `getCreatorIconPathForModelId()` added to `@storyteller/model-list` (model id → creator icon path, desktop/webapp aware).	2026-06-13 17:25:40 -04:00

BFlat	2818831a66	Webapp: seed new folders with selection + marquee selection fixes (#1634 ) - New folder keeps selection: "Add to folder > Create new folder" now drops the selected items into the folder on create instead of leaving it empty (webapp library + desktop gallery modal) - Marquee dead below the fold (main bug): flex-column scroll parent shrank the page root to one viewport; presses lower down missed the handler. Fixed with `shrink-0` so the root spans the full scroll height - Edge auto-scroll: holding a drag near the top/bottom edge scrolls the list so you can keep selecting past the viewport in one drag (anchor compensated for scroll; virtualized tiles stay selected) - No blue highlight: `select-none` on the page (inputs opted back in) blocks accidental text/image highlighting and stops it competing with the drag - Rectangle no longer covers the top bar: visible marquee box clamped to the gallery viewport; selection hit-testing stays unclamped	2026-06-12 10:48:25 +07:00

Tanish Manku	10f8297c1f	Fix desktop video generation ignoring selected resolution (#1631 ) The desktop video promptbox built the GenerateVideoRequest without ever setting `resolution`, so generation always omitted it and the backend fell back to the model's default (720p) — and billed for it. The cost preview reads the same store value and sends it, so the preview was correct (e.g. 117 for 480p) while the charge stayed at the 720p price (240). Populate request.resolution in buildRequest, mapping the store's legacy display string ("480p"/"720p"/"1080p") to CommonResolution, guarded on the model exposing resolutionOptions. Also fix useImageCostEstimate (webapp) omitting `quality` from its effect deps, which meant the image cost preview didn't refresh when only the quality option changed.	2026-06-11 14:48:48 -07:00
