The interactive canvas (selection outlines, transform handles, binding highlights, collaborator cursors, snap lines, scrollbars) was still composited through `filter: invert(93%) hue-rotate(180deg)` in dark mode (#10578 only de-filtered the static canvas). The canvas covers the whole viewport and repaints on nearly every pointer move, so browsers that composite in software (Firefox/Zen on software WebRender or with hardware acceleration disabled) paid for a full-viewport color-matrix pass per frame and dropped from 120fps to ~40fps during marquee/drag. Light mode was unaffected. Colors are now mapped in JS via `applyDarkModeFilter`, like the static canvas. Hardcoded dark-mode values are the exact post-filter equivalents of the previous ones, so rendering is unchanged, with two intentional exceptions: - collaborator cursors and remote selection outlines render in the collaborators' actual colors (matching their avatars) instead of inverted ones (per the existing TODO in clients.ts) - the lasso trail now uses the theme's `--color-selection` like the marquee selection, instead of a hardcoded light-theme purple that never matched in dark mode `--color-selection` for the dark theme now holds the actual rendered color (#b4b0ff); hosts overriding it no longer need to pre-invert.
