Detailed Description

Loads a QSS stylesheet from the built-in :/stylesheets/ resource tree and resolves every wstheme(RoleName) token by looking up RoleName in the current theme's color map.

Split out of ThemeManager so the loader logic — stylesheet path sanitization, QSS read, token regex, role-enum lookup — lives alongside the other theme helpers under ui/qt/utils/themes/.

Stateless: every call reads fresh resource contents and resolves tokens against the token map the caller provides. ThemeManager is the usual caller and passes its own themeColors_ / isDarkMode().

load()

QString ThemeStyleSheetLoader::load ( const QString & name, const TokenMap & tokens, bool isDarkMode )

static

Load :/stylesheets/<name>.qss and return its contents with:

• every wstheme(RoleName) token replaced by the resolved #rrggbb hex of the corresponding ThemeToken, picked from tokens using isDarkMode to choose the light/dark side;
• every literal wsmode% occurrence replaced by the string "dark" or "light" — intended for picking mode-specific asset filenames inside image: url(...) rules, e.g. image: url(:/stock_icons/14x14/x-filter-dropdown.wsmode%.png); The wsmode% placeholder takes no arguments and is a plain text substitution; it runs before the wstheme(...) regex pass.

Returns an empty QString on any of:

• name is empty or contains illegal characters / path traversal attempts (.., leading /, leading ., backslash, etc.)
• The resource file cannot be opened.

Tokens that don't resolve (unknown role name or missing color in the map) are stripped from the output and a qWarning is emitted — Qt's QSS parser is all-or-nothing per object, so leaving a literal wstheme(Foo) in place would silently drop the entire rule on the first typo; stripping keeps the rest of the rules valid and the warning surfaces the typo.

Parameters

name	Logical name under :/stylesheets/, without extension (e.g. "widgets/learn-card").
tokens	Current theme's color map.
isDarkMode	Which side of color pairs to select.
