/* For pure display, force a modified render */
.deep-tamil-130
font-family: 'Noto Sans Tamil', 'MCL Kannamai', fallback;
font-weight: 500; /* Force medium weight to emulate Kannamai's thicker style */
transform: scale(1.01); /* Micro-zoom to hide broken anti-aliasing */
MCL Kannamai’s horizontal strokes can disappear at large sizes. Add a text-shadow without blur to fake thicker horizontals: mcl kannamai tamil font 130 better
.tamil-large
text-shadow:
0 0.5px 0 rgba(0,0,0,0.2),
0 -0.2px 0 rgba(0,0,0,0.1);
