Resolves the AiPostWizard conflict and completes the feature:
- i18n parity: brand_colors_label + brand_colors_description in all 15 locales
(was en/es/pt-BR only, which broke LocalizationParityTest).
- Reworked the two-button toggle into a Switch with an explanatory description
(matches the settings Switch/card pattern).
- Only shown for templates that honor the flag: added appliesBrandVisuals() to
the AiContentTemplate contract (ImageCard=true, tweet cards=false), exposed as
applies_brand_visuals in the create-page DTO, and gated the toggle on it — so
it no longer appears (as a no-op) for tweet-card styles.
- Tests: TemplateContractTest covers appliesBrandVisuals for all templates.
- Assert GeneratePostContentRequest rejects a prompt over the shared max, so the
editor's limit is pinned explicitly (not only implied by the create wizard).
- Assert the create wizard accepts a prompt at exactly the minimum length,
complementing the below-minimum rejection.
The counter added earlier drifted from the backend in two ways: it counted
UTF-16 code units over the raw (untrimmed) value, while the backend measures
Unicode characters (mb_strlen) over the trimmed value that is actually sent —
so emoji or trailing whitespace could falsely turn the counter red and block
the button. The 2000 limit was also copied into three places, and the wizard's
frontend `>= 3` minimum had no backend counterpart.
- Add App\Support\AiPromptRules as the single source of truth for the prompt
bounds; both StartPostCreationRequest and GeneratePostContentRequest use it.
- Add min:3 to the create wizard endpoint so front and back agree (the editor's
generate-content flow keeps `required` — it has no counter to mirror).
- Count code points over the trimmed value in AiPostWizard so the counter and
the submit gate match what the backend validates, matching AltTextDialog.
- Cover min/max/boundary in PostAiCreateTest.
The image pipeline already threads `applyBrandVisuals` through
`TemplateContext` -> `PostImagePipeline` -> `TemplateImageGenerator`, but it was
hardcoded to `true` at the dispatch site, so generated images always used the
workspace brand palette with no way to opt out.
Expose the choice in the create wizard: a "Brand colors" / "Let AI decide"
toggle (shown only when images are generated). The flag flows
front -> `StartPostCreationRequest` (`apply_brand_visuals`) ->
`PostAiCreateController@start` -> `StreamPostCreation` -> `TemplateContext`,
defaulting to `true` so existing behavior is unchanged when the field is absent.
Instagram carousels were stored as content_type=instagram_carousel, which the
publisher's match() did not handle — publishing failed with "Unsupported
Instagram content type: instagram_carousel" for any post created via API, MCP,
or template (the AI flow worked only thanks to an inline band-aid that rewrote
carousel to feed before saving).
A carousel is just an Instagram feed post with multiple images: the editor,
preview, and publisher already treat a multi-image feed as a carousel. So
instagram_carousel is a generation format, not a stored content type. Remove it
from the ContentType enum entirely; it now lives only as an AI generation-format
string (wizard card + slide structure + carousel templates are untouched), and
posts always persist as instagram_feed.
- ContentType: drop the InstagramCarousel case; InstagramFeed maxMediaCount 1 -> 10
- StreamPostCreation: resolvedContentType() maps carousel -> feed; band-aid removed
- StartPostCreationRequest: accept instagram_carousel as a generation format
- Frontend: carousel becomes a wizard-local AiFormat; UI/UX unchanged
- API/MCP now reject instagram_carousel as a content_type (Rule::in no longer lists it)
Core changes:
- Replace Unsplash slide pipeline with gpt-image-2 via Laravel AI SDK.
New AiImageClient builds prompts from a Blade template seeded by the
workspace's ImageStyle enum, content language, brand color (mapped to a
human-readable name via HexColorName helper) and brand description.
- Drop Template B from TemplateImageGenerator: every slide now renders as
Template A (full-bleed photo + bottom gradient + white/grey overlay).
Removes renderTemplateB, roundCorners, blendHex, ensureContrast and the
closing-slide pipeline.
- StreamPostCreation creates the Post directly and dispatches
PostCreationReady with post_id; the wizard kills its preview step and
redirects straight to the post editor on completion. Finalize endpoint
removed.
- New Workspace.image_style enum field with an 8-option visual picker
shared by /workspaces/create and /settings/workspace/brand via a single
BrandForm component (autofill is a prop). 8 sample webp thumbs ship
under public/images/branding/image-styles/.
- Media items gain optional source ('ai'|'unsplash'|'giphy') and
source_meta (recipe needed to regenerate AI images later); the gallery
picker tags Unsplash/Giphy attachments.
- Brand-color autofill: new CssColorFrequencyExtractor parses every
hex/rgb/hsl value in the homepage CSS, clusters perceptually similar
shades in CIE LAB (Delta E 76 < 12), filters neutrals and returns the
most frequent cluster. Solves Tailwind/utility-CSS sites where no
semantic --primary variable is exposed.
- Credits: gpt-image-2 metered at 15 credits/image (low quality default).
- Layout: AuthSplitLayout right column is sticky/h-svh so the form
textarea growth no longer stretches the marketing slider.
- i18n cleanup: localized labels follow the no-em-dash convention.
