#app has width:100vw and a 1px border with default content-box box-sizing,
so its rendered size is 100vw+2px which overflowed body → unwanted scrollbars.
tauri.conf: resizable=true, min 220x240, default 300x320.
BlockRing: SVG scales via viewBox, claims remaining vertical space.
#app uses flex column with sections flex:0 0 auto — content reflows when window resized.
Bumped --bg opacity from 0.78 to 0.93 so files behind the widget don't bleed through.
Themed scrollbars subtle when they do appear.
The widget now spawns 'claude' via portable-pty, sends /usage, parses the
three rendered bars (Current session / Current week all / Current week
Sonnet), and shows the real percentages in the ring + weekly bars. A
background task refreshes every 5 minutes; the title-bar refresh button
forces an immediate fetch.
Drops the cap-tuning UI and tier card from Settings; adds a 'claude command'
override (e.g. 'wsl.exe -- claude' for Windows-host widgets reading WSL
credentials) and a refresh-interval setting. Fixes title-bar buttons getting
swallowed as drag attempts via data-tauri-drag-region="false".
