Version 1.9.0 M5.1 Released

M5.1 is a compatibility-preserving correction built from Version 1.9.0 M5. It does not add a new gameplay system or change Lost Mountain balance.

Fixed: Story Chronicle controls

The Story index used fixed minimum widths that totaled 496 CSS pixels even when its actual sidebar was only 374–421 pixels wide. Because the panel deliberately hides overflow, the Read Status selector was clipped and the Mark All Read button collapsed into a narrow vertical control.

M5.1 replaces that row with a bounded responsive grid:

• search uses the full row;
• Story Arc and Read Status share a second row;
• Mark All Read uses a full-width action row;
• very narrow screens switch to a single column;
• every control remains inside the Story panel at 85%–130% interface scale.

Improved: Chronicle summary

The former sentence-like completion line could leave “Read” isolated on a separate line. It is now split into a descriptive line and two responsive status badges.

Additional hardening

• refreshed the browser cache token and build identity;
• updated the page metadata to describe the completed Lost Mountain campaign;
• added dedicated Story layout tests in English and German;
• added an overflow/control-bounds audit for all 28 primary screens;
• added an internal-workspace audit for 82 tab states;
• retained all M5 Homecoming, reclamation and save-safety behavior.
