v5.9.2

• Radial progress bars: clearer contrast between the read and unread halves on the default colour scheme.
• Default bottom margin reduced to 10px (was 25px). New blank presets now start with the canonical defaults, matching what "Default" gives you in the margin editor.
• Border thickness setting now applies to bars with custom colours enabled (previously it silently dropped to 1px when no per-bar value was set).
• %chap_title_1 / %chap_title_2 / %chap_title_3 render correctly when used without %chap_title alongside.
• %light_pct and %warmth_pct now include the % suffix automatically, matching %book_pct and %chap_pct.
• Tokens placed directly next to each other (e.g. %nightmode%chap_title_1 with no separator) render correctly.
• Adjusting brightness or warmth refreshes overlay icons and percentages promptly instead of waiting for the next page turn.
