5193-5203: 🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy liftScale complete widget geometry and typography.
These calls scale widget positions, but several helpers retain fixed heights, padding, font sizes, handles, and labels. At 200% zoom, a
TextInputgets twice the width but remains 36 pixels high with 14-pixel text. Checkbox, switch, slider, badge, and label content have the same problem.Pass the zoom factor into each helper. Scale all visual dimensions inside each helper. This is required for page zoom to apply consistently to widgets.

Calculate the highlight top from the text baseline.
DrawCommand::Text::y is the text baseline. Line 54 uses it as the rectangle top. This places the highlight below most glyphs.
Subtract an estimated ascent from y. Add a regression test for the vertical bounds.
Proposed fix
- (left, y, w, h)
+ let top = y - size;
+ (left, top, w, h)📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Emit one FindHit for each substring occurrence.
This guard emits only one hit for each text command. For example, "foo foo" produces one result for "foo". Find navigation cannot visit the second occurrence, and the result count is incorrect.
Enumerate all occurrences. Store match-specific offsets or bounds. Apply the same contract to widget, console, and list collectors.

Apply canvas transforms to Find bounds.
This branch ignores Save, Restore, and Transform. Text rendered after a translation or scale keeps its original bounds. The highlight and navigation target then use the wrong location.
Maintain a transform stack while processing commands. Add translation, scale, and nested save/restore tests.

Keep scrollbar calculations in one coordinate system.
These lines store the viewport height in unscaled layout units. Lines 5329-5358 then use that height directly as physical pixels for the scrollbar thumb and drag calculations.
At 200% zoom, a 600-pixel viewport becomes 300 layout units. The scrollbar therefore uses a track model that is half the visible physical height. The thumb has the wrong size and cannot traverse the full track.
Convert the scrollbar values back to physical units, or perform all scrollbar calculations in layout units and scale the rendered geometry and pointer deltas.

Use the themed hover color for the Allow button.
The light palette gives this button a dark primary() background and a light primary_fg() foreground. The existing hardcoded hover background is also light, so the label loses contrast while the pointer is over this permission action.
Use theme::primary_hover() for the hover state.
