Subject: [PATCH] fix(cliamp): readable accent + correct fg/bright_fg
 brightness

The cliamp theme-set hook mapped accent=color4 and bright_fg/fg=color15/color7
verbatim. On monochrome/matte palettes color4 is a dark, low-contrast colour,
yet cliamp uses accent for the title, seek bar and the key-hint background ->
those become unreadable. Some palettes also define color15 darker than color7,
which inverts cliamp's normal/dim text brightness.

Pick bright_fg/fg by luminance (bright_fg always the brighter), and fall back to
a readable, preferably coloured accent when color4 is too close to the bg.
