- ArticleCard: derive safeHref from article.url and reset image-failure state
when the article changes, so in-place replacements re-evaluate correctly
(clears the Svelte capture warning; build is warning-free again).
- Downweight paywalled stories below readable ones (stable sort) when composing
the daily five and in feed results — the brief now leads readable and rarely
hands over a locked door.
- review_sources gains a 'paywall-heavy' advisory flag (Nature, New Scientist
flag at 100%); never auto-deactivates.
- New Scientist/Nature kept active but no longer reach the daily five; they
remain browsable with the label + Replace.
- Tests: brief readability preference + paywall-heavy flag (79 total).
