feat: Зеро-персонаж, auto-publish, auto-series, channel-stats, fallback covers
- Персонаж Зеро: 23 позы (zeroCharacter.js), скрипты генерации - Auto-publish статей в TG: multipart upload, кнопки, режим alternating Zero/cover - Fallback цепочка обложек: aiprimetech gpt-5.5 → Pollinations → local SVG (6 палитр) - Auto-series: Claude haiku определяет серию для каждой статьи автоматически - Channel stats: подписчики, история, delta 24h/7d - Photo-search: Yandex API, профили доменов, Redis лимиты - Scheduled posts runner: backfill, preview, queue, cancel - promptBuilder: author_persona Зеро, голос от первого лица - Fixes: dollar-placeholder bugs в PATCH channels/autogen, listArticles фильтры - AI model: gpt-5.5 для image generation

Character: a small, friendly mascot named Zero.
|
||||
Body: a soft rounded square shape (like a plump pixel or a chubby tetris block), about the size of a small companion creature.
|
||||
Color: bright emerald green (#10b981) with a slight gradient to teal, soft and matte.
|
||||
Face: two simple round black dot eyes, a small understated mouth that expresses the current emotion.
|
||||
Personality: friendly, curious, enthusiastic, a bit nerdy.
|
||||
Style: clean modern vector illustration, flat design with soft shading, no outlines.
|
||||
Background: warm off-white (#fafaf9) with subtle geometric shapes in light teal/emerald, like Notion/Linear/Anthropic editorial illustrations.
|
||||
Composition: 1:1 square format with comfortable padding, character is the main focus.
|
||||
Strictly: no text, no letters, no logos, no humans, no realistic robots, no glowing nodes, no circuits.
