Text reads on every surface, and accordions are outlines

An audit of every settings surface found 94 runs of text below WCAG AA in a light scheme and 98 in a dark one. None remain. Secondary text is a measured colour instead of half opacity, badges and buttons take text measured against their own fill, alerts are tints with measured text, and a dark scheme no longer shows a white stripe beside the vertical tab bar. Accordions are outlined cards rather than grey slabs, and profile selector rows show a pointer.

On a light scheme, settings descriptions sat in pale grey on grey panels, the profile selector's ENTER hint was white on light grey, an SSH badge was white on near-white and a Telnet one black on bright blue. Accordions were stacked grey slabs, and on a dark scheme a full-height white stripe ran between the vertical tab bar and the tab.

The causes were few and global. Secondary text was the foreground at half opacity, which is a different colour on every surface; ThemesService now derives --theme-muted-fg to reach 4.5:1 on the page, both raised panels and both hover fills. Bootstrap compiles each .text-bg-* text colour at build time against its own palette while the fill is the scheme's runtime colour, so badges and buttons now read a colour measured against their own fill, at rest, hovered and pressed. Derived colour pairs whose foreground is text floor at 4.5 rather than 4.

• A badge fill too close to the page gets a one-pixel inset edge at 3:1, and an alert is a 14% tint of its colour with text and border measured against that tint.
• Each accordion group is an outlined card on the page: the header carries the weight and a keyboard focus ring, the body has no fill, and the chevron follows the text colour instead of a compiled blue that measured 1.14:1 on a dark scheme.
• The white stripe was the vertical tab bar's resize splitter, transparent over a body that is transparent on purpose, showing the window's white backing. It now paints the tab bar's own colour.
• Rows in the profile selector are anchors with no link, so they showed a text caret; they show a pointer now.

• Measured on AtomOneLight and Afterglow, plus the two default schemes for alerts. Another scheme is floored by the same rules, not individually measured.
• Not yet audited: the Claude side panel and hover card, the link hover card and preview pane, the SFTP panel, menus and toasts.
• Plain links outside alerts still use Bootstrap's blue, which falls below AA; no audited page shows one.
• The theme's primary and info colours are the same, so their badges and alerts cannot be told apart.
