A read theme's name is an Ellipsis that gives way beside its mode badge,
so a long name keeps the badge inside a 280px box. parse_hex reads #rgba
as VS Code does, each digit doubled, so a theme with a four-digit color
reads. Tests hold the badge inside the box and read #0008 as black at
0x88 alpha.
settings::read_vscode_theme reads a VS Code color theme, comments and
trailing commas and all: its type picks the mode, its colors and token
scopes name what they give, and the rest keep Ely's palette of that mode.
settings::ThemeImporter takes one dropped or browsed for, shows its name,
mode and count, and hands it over on Apply; a file that does not read
says why. theme::syntax_themes offers Ely's code colors, Quiet and Paper,
chosen through settings::SyntaxThemePicker, radio cards with a line of
code in each palette. A card's words now shrink as a plain block, so a
preview wraps inside the card at 280px.
