/* * Persona v0.78 — global grayscale mode. * * Activated by the ``data-grayscale="1"`` attribute that ``base.html`` * stamps onto ```` whenever the ``grayscale_mode`` kv_settings * row is ``"1"``. The rule below wraps the entire document in a CSS * ``grayscale(1)`` filter — accent colours, thumbnails, tag pills, and * every other rendered pixel collapse to neutral tones for * distraction-light reading. * * The default (``data-grayscale="0"`` or absent) keeps full colour * untouched: this sheet ships zero rules outside the * ``body[data-grayscale="1"]`` selector so it is safe to include on * every page regardless of the stored setting. */ body[data-grayscale="1"] { filter: grayscale(1); }
