CARD - mechanics that cannot be expressed as a utility
|
|
----------------------------------------------------------------------------
|
|
Everything token-driven lives in the TSX as a tier-2 utility
|
|
(bg-surface-raised, text-text-accent, rounded-surface, ...). This file only
|
|
holds the three things a utility cannot do:
|
|
|
|
1. paint an exported SVG asset in the current token colour (mask),
|
|
2. the whole-card link overlay + its focus ring,
|
|
3. the hover transitions, which need a duration/easing token pair.
|
|
|
|
Class names are prefixed `sh-card` because this file is imported by the
|
|
component rather than by app/app.css, so it is not scoped by anything else.
|
|
|
|
Everything lives in @layer components so a Tailwind utility passed through
|
|
`className` (`rounded-surface`, `text-text-secondary`, ...) still wins.
|
|
The layer statement is a defensive no-op when app.css has already declared
|
|
the same order, and makes this file correct on its own if it ever loads first.

ICONS
|
|
The SVGs exported from Figma (public/assets/icons/*.svg) have the brand
|
|
green baked in as stroke="#008764", which would be wrong on the dark surface
|
|
and inside the accent chips. Drawing the asset as a mask over a currentColor
|
|
fill keeps the exact exported geometry while the colour comes from whichever
|
|
semantic token the parent set. Size is set per instance so each icon keeps
|
|
its designed box (14px, or 10px for the stat trend arrow).

WHOLE-CARD LINK

entire card is clickable while the title stays the accessible name and no

interactive element is nested inside another.

|

anything that has to stay clickable above it (the team card's social links).
