v0.4.0

Added

• GPT Image 2 and GPT Image Mini are now available as first-class models. The previous single "GPT Image" entry is split into three tiers in SUPPORTED_MODELS:
  • openai-2 → GPT Image 2 (gpt-image-2) — OpenAI's flagship image model with 2K/4K resolutions and aspect ratios from 3:1 to 1:3.
  • openai-mini → GPT Image Mini (gpt-image-1-mini) — budget tier.
  • openai → GPT Image 1.5 (gpt-image-1.5) — retained for backwards compatibility with existing user preferences.
    All three share a single apiKeys.openai slot, so existing keys keep working without re-entry.
• Quality control for OpenAI models. New toolbar dropdown (visible only when openai-2 or openai-mini is selected) with Auto / Low / Medium / High. Persisted per-user as settings.openaiImageQuality via UserSettings, and passed through to both generation and refinement calls. gpt-image-1.5 ignores this parameter (it doesn't support quality).
• Expanded aspect ratios for GPT Image 2. New OPENAI_2_ALLOWED_ASPECT_RATIOS adds 16:9, 9:16, 3:1 (banner), and 1:3 (skyscraper) on top of the legacy three. Concrete pixel sizes (e.g. 2048x2048 for 2K square, 2304x768 for 3:1) are picked to satisfy OpenAI's constraints (edges multiples of 16, long:short ≤ 3:1).
• Admin users table redesign. The 11-column table is collapsed to a scannable 4-column layout:
  • User — display name with a rotating chevron that expands an inline details panel showing username, email, and created date (with hover-for-full-timestamp on the shortened date).
  • Last seen — relative time (2 days ago, 3 months ago, Never) with a hover popover showing the exact timestamp.
  • Status — row of five 40×40 circular icon pills with hover tooltips for model, Gemini key, OpenAI key, admin role, and suspension state. Active pills are tinted (teal / amber / red); inactive are ghost-dim.
  • Actions — sticky to the right edge with a visible bordered ⋯ button so it's always in view regardless of horizontal scroll.

Changed

• services/openaiService.ts signature is now generateOpenAIImage(prompt, config, apiKey, { modelId, quality, systemPrompt }). modelId maps UI ids (openai-2 / openai-mini / openai) to OpenAI API model names, and quality is only sent to models that actually accept it.
• getApiKeyForModel in App.tsx now routes all three OpenAI ids to apiKeys.openai — no schema change, no re-entry required.
• Settings page description for the OpenAI API key now reads "Used by GPT Image 2, GPT Image Mini, and GPT Image 1.5" so the shared-key behaviour is obvious.
• services/aspectRatioService.ts splits the OpenAI allowed-ratio logic by model id so openai-2 gets the expanded set while openai and openai-mini stay pinned to the legacy three.
• Model labels updated across ControlPanel, ImageDisplay, RecentGenerations, and the admin stats service: openai-2 → "GPT Image 2", openai-mini → "GPT Image Mini", openai → "GPT Image 1.5".
• Admin action button is now a bordered pill (w-11 h-11), meeting the 44×44 touch-target rule and making the previously-ghosted ⋯ actually discoverable.
