matmoul 6a37c7c1e8 feat: add pow10 and exp arithmetic operations 2026-05-16 23:15:22 +02:00
matmoul 5f2d18df99 fix(calc-02): constrain keypad area with internal scrolling 
Wrap the keypad, function, and trig panels in a dedicated scroll area so the calculator shell can use a fixed grid layout without overflowing the viewport. Also update panel styling to preserve spacing and scrollbar behavior.

matmoul 813fae1b61 refactor(calc-02): simplify calculator layout structure 
Move the display and button panels into a single wrapper and rely on
viewport-height sizing with hidden page overflow to keep the calculator
contained. Also trim redundant panel-specific layout rules and styling.
