PHP 8.3 TypeError and Error extend \Throwable but NOT \Exception,
so catch(\Exception) silently drops them — explaining why the
generation pipeline fails at the publishing step with no activity
log entry. Now every catch in the generation path catches
\Throwable and logs the exception class name for diagnostics.
Bump to v0.2.7.

Replaces Cloudflare Workers AI (FLUX.1 schnell) as the default image
provider with OpenRouter, which offers FLUX.2 Pro, Seedream 3.0,
Gemini Flash Image, and GPT Image 1 at comparable or better pricing.
- New provider class (3-file split: provider, pricing, support) reuses
the existing OpenRouter API key and Cloudflare AI Gateway
- Admin settings: new Image Provider dropdown (openrouter/cloudflare),
model picker shows all available image models from both providers
- Image pipeline auto-selects the configured provider at construction
- Cost logging now uses actual model name instead of hardcoded flux-1-schnell
- Default model changed to black-forest-labs/flux-2-pro ($0.03/image)
- Unit tests for pricing resolution and provider response parsing
Cost impact: FLUX.2 Pro at $0.03/image vs schnell at $0.0007/image —
~43x more expensive per image, but dramatically better quality. At 2
images/article × 1 article/day = ~$1.80/month. Seedream 3.0 ($0.003)
available as a budget alternative.

FLUX.1 schnell requires width and height to be divisible by 8.
The default OG image size 1200×630 has 630 % 8 = 6 remainder,
causing HTTP 400 on every image generation call.
Changes:
- Pipeline default height 630 → 632 (nearest 8-aligned value)
- Provider now rounds any dimension to nearest multiple of 8 as
a defensive guard before sending to the API

- Wrap cost_usd accumulation in is_wp_error() guard so WP_Error
returns from generate_image_a/b don't crash on array access
- Add PRAUTOBLOGGER_DEFAULT_IMAGE_STYLE_SUFFIX to test bootstrap
- Add is_wp_error, sanitize_title, esc_html__ mocks to ImagePipelineTest

Union types (array|WP_Error, int|WP_Error, string|WP_Error) require
PHP 8.0+. Removed return type declarations while keeping @return
docblocks intact for IDE/static analysis support.

Completes the image + A/B experiment workstream by integrating
image generation into the post publishing pipeline.
New classes:
- class-image-pipeline.php: Orchestrates A/B generation (article-driven
Image A → featured; source-driven Image B → post meta). Each image
independently fallible; article publishes even if both fail.
- class-image-prompt-builder.php: Synthesizes visual prompts from article
title+content and Reddit source data. Appends CEO-locked 90s infomercial
style suffix. Keeps prompts concise for FLUX.1 quality.
- class-image-media-sideloader.php: Downloads image bytes, creates temp
file, sideloads via media_handle_sideload(), sets alt text and metadata,
cleans up temp files.
Changes to existing files:
- Publisher.attach_generated_images(): Runs image pipeline post-creation,
sets _thumbnail_id (Image A) and _prautoblogger_image_b_id (Image B).
Errors logged but don't block post publication.
- Settings: prautoblogger_image_enabled (toggle, default off).
Tests:
- ImagePipelineTest.php: Orchestration, cost tracking, graceful failures.
- ImagePromptBuilderTest.php: Prompt generation, length limits.
Docs:
- ARCHITECTURE.md: New step 6b in data flow, new files in file tree.
- CHANGELOG.md: Commit 1a/1b breakdown.
