spi9 App font, typography and webfont guide

In Dhaka we first checked the font balance after opening the spi9 App; how fast the headings, menus, and buttons read is the main point here.

On Bangladeshi phones, when the webfont loads correctly the screen looks much cleaner, and the text doesn't get cluttered on bKash, Nagad, Rocket and mobile data.

What we saw in font setup

1. Heading weight

Bold headings stand out, but if too heavy, reading on Dhaka's mid-range Android phones is hard; the balance is good here.

2. Line spacing

When line-height is correct, sports, slot and app menu feel separate; 1.4 to 1.6 range felt most comfortable.

3. Bengali Rendering

Bangla glyphs don't break; if the webfont loads quickly, the characters don't cluster in one place, so the page stays clean.

4. Loading behavior

Even on slow networks, the first render arrives quickly; the rest of the text stabilizes gradually, so less jitter.
