/* Self Forming — the shared base stylesheet.
   Reset, page layout, typography, shared controls (buttons, form rows, lists, dialogs); no edition-specific values.
   Everything else is shipped by the plugin that owns the screen (the .css files in plugins/<id>/web: core-chat, core-conversations,
   the Settings sections, the dev tools) and the look is a plugin too (plugins/look-<name>/web/look.css). They are all bundled in the
   generated builtin-styles.css (linked right after this file) and are also the plugins' `styles` contributions.
   Flat paper, dark ink, monospace type; no animations on screen changes; nothing bundled, nothing from the network. */
