/* ==========================================================================
   MD.KONVI.CH — Konvi-inspired theme for CodiMD
   --------------------------------------------------------------------------
   Loaded after CodiMD's own stylesheets. Two jobs:
     1. A self-contained landing page in the konvi.ch colour world.
     2. Recolouring the editor chrome (navbar, buttons, links, night mode).
   Palette is taken from konvi.ch: teal primary, amber accent, slate neutrals.
