Introduce a new rotator button tile and mirror auto-rotation feature. CSS adds styles for rotator buttons and locked mirror display. JS: add legend entry and rotatorButtons config, track activeRotatorButtons and rotatorIntervals, implement rotateMirrorStep, isMirrorControlledByButton, syncRotatorButtons and stopAllRotatorButtons; wire rotator behavior into traceLaser and loadGrid so rotator buttons activate intervals that rotate target mirrors automatically and lock out manual rotation. Refactor rotateMirror to reuse rotation step logic and ensure rotator intervals are cleared when advancing levels.
Adjust UI visuals: change page background to #FFF6E5, increase main container border-radius from 10px to 150px, and soften toolbox corners (5px → 15px). Add a new .game-title CSS rule (responsive font-size, weight, color, letter-spacing, centered) and insert an <h1 class="game-title">Mirror Game</h1> into the game template. These are visual polish changes only; no gameplay logic was modified.
Add per-cell laserSegments tracking and use it to render correct laser orientation: introduce laserSegments global, reset it at trace start, populate entries when tracing, and consult it in loadGrid to choose horizontal vs vertical classes. Update UI styling from a dark to a lighter theme (body and main backgrounds, cell/empty/mirror/wall colors and laser gradients), remove some borders/fit-content sizing, and add a "map" class to the map container in the HTML. These changes fix laser orientation rendering and refresh the game's visual theme.
Add a small utility function in web/assets/js/index.js that increments an element's CSS rotation by 45 degrees. The function reads the element's inline transform (handling an empty value), parses the current rotation angle modulo 360, and sets the new rotate(angle+45) value.
