v1.2.0

Added

• Dark Theme: Every screen has a dark counterpart, warm charcoal rather than black, with the sage green carried through and a wordmark drawn for it. Auto, Light and Dark sit in the profile menu, and on the sign-in, setup and password screens.
• The choice is remembered and applied before the page paints, so a dark session never flashes white, and it reaches any other tab already open. The landing page follows the system the same way.

Changed

• The knowledge graph exports with a transparent background, as an SVG or a PNG, so it sits on whatever it is dropped into, and is drawn light whichever theme it was exported from.
• A shared result card stays on light paper, since it is read wherever it is sent rather than here.

Fixed

• Every colour and corner the stylesheet asks for now has a name that exists. Five were referenced and never defined: the generation pills lost their background and their pending dot, an empty-state line its softer grey, and a dropdown row its rounded corners.
• The zoom controls on the knowledge graph carry icons rather than characters, so they sit level with Reset beside them.
• The theme control is a radio group, so the arrow keys move through it and it reads as one choice of three rather than three switches.
• A browser that refuses local storage no longer takes the app down on load.
