Each experience task row closed with a solid `fa-bolt` glyph. The reference
marks the same slot with the colour `trend-color` sprite followed by "+ N",
and uses that sprite for the 成长体系 heading as well, so the level page also
carried a stray `fa-chart-line` there.
The sprite already ships in the theme (`jiosvg-trend-color`); its path data is
byte-identical to the reference sheet. Both slots now render it, sized to
match the reference (`icon mr6 em09` for the rows, `icon mr6 em12` for the
heading). The "动态" rows keep their wording without a "+", which is how they
read before.
The check-in experience badges in src/Credits/Signin.php stay on
`fa-line-chart` — the reference uses the same monochrome glyph there.
Verification: rendered the real level page through a PHP stub — all ten task
rows emit `#icon-trend-color`, the only Font Awesome glyph left is the
"每日详情" arrow, matching the reference. Screenshotted against the real
stylesheet. A contract test pins both sprite usages and rejects a regression
to `fa-bolt` / `fa-chart-line`; 862 widget/navigation tests pass.
