The main board of Darśana is almost complete.

This revision focuses on refining the audio power and signal layout, separating AGND/DGND domains, and finalizing the analog output paths (DAC → Line / Phones).

• Introduced a local `+5V_AUDIO_Analog` plane on Inner2 exclusively for the headphone amp (TPA6130A2).
• This simplified routing and reduced coupling around the charge pump region.
• Maintained at least 2mm clearance between the charge pump loop (CAPP/CAPM/VNEG) and all power traces.
• Ensured continuous AGND on Inner1, no necks or splits.

With all components placed and DRC passing cleanly, the PCB measures 294 × 99 mm — fitting perfectly inside the planned 296.6 mm internal width enclosure.

It was a demanding phase, but the layout came together faster than I expected — a relief, honestly. There are still rough edges to refine, and I can already see places that could be improved with more polish. Fortunately, there’s no rush. I’ll take as much time as needed to make it right.
